qr code is more developed than barcode
While a barcode only holds information in the horizontal direction, a QR code does hold information in both horizontal and vertical directions. Due to this, a QR code holds hundreds of times more information than a barcode.
With that being said they have different purposes, and there about the same developed as each other, unless you count how much information they can store.
A license plate has 7 characters. Each character can be a capital letter or a digit except for 0. How many license plates are there in which no character appears more than once and the first character is a digit?
a. 9 P(35, 6)
b. 9 P(34,6)
c. 9.(35)^6
d. 9.(35)^6
Answer:
b. 9 P(34,6)
Explanation:
Since the 1st character of the number plate is the digit, therefore, there are nine possible ways to select them from digits 1 to 9.
And in the license plate there are 7 characters, the first character is counted before and the remaining 6 characters that can either be a digit or a letter has to be considered.
Now there are in total 34 symbols remaining form a total of 26 letters and 8 digits. They can be placed as 34x33x32x31x30x29 ways = P(34, 6) ways.
Therefore in total for all the characters there are 9 x P(34, 6) different ways.
What is result of executing the following code?
public class Question11 {
private static int x = 1;
public static void main(String[] args) {
int x = 5;
System.out.printf("local x in main is %d%n", x);
useLocalVariable();
useField();
useLocalVariable();
useField();
System.out.printf("%nlocal x in main is %d%n", x);
}
public static void useLocalVariable() {
int x = 25;
System.out.printf(
"%nlocal x on entering method useLocalVariable is %d%n", x);
++x;
System.out.printf(
"local x before exiting method useLocalVariable is %d%n", x);
}
public static void useField() {
System.out.printf(
"%nfield x on entering method useField is %d%n", x);
x *= 10; // modifies class Scope’s field x
System.out.printf(
"field x before exiting method useField is %d%n", x);
}
}
Answer:
Explanation:
With the main method int the question calling the useLocalVariable and useField variable various times and then also printing out the variable using the printf method. The output of executing this code would be the following...
local x in main is 5
local x on entering method useLocalVariable is 25
local x before exiting method useLocalVariable is 26
field x on entering method useField is 1
field x before exiting method useField is 10
local x on entering method useLocalVariable is 25
local x before exiting method useLocalVariable is 26
field x on entering method useField is 10
field x before exiting method useField is 100
local x in main is 5
Greedy Algorithm Design
A couple wants to buy n major items. They will buy one item per month. They will buy all of their items at the CrazySuperStore. Due to the current economy, it is known that at some point in the future there will be a single price hike on all items at the same time, but due to the uncertainty of economic processes, it is not known when that price hike will occur. For each of the n items the couple wants to buy, both the current price, ai and the future price, bi (bi > ai), are known. (Note that the individual price hikes on items may vary. For example, one item may go from $100 to $105 while another might go from $300 to $400. They only assumption you may make about the prices is that the second price is strictly higher than the first and that you have access to all before/after prices.) Devise a greedy strategy so that the couple is guaranteed to minimize the amount of money they spend on the items. Assume that no matter what, the couple will buy all items. Clearly describe your strategy and intuitively (or formally) prove why it's optimal.
Answer:
The algorithm is as follows:
1. Start
2. Get the number of items (n)
3. Get the current price of the n items (a1, a2..... an)
4. Get the possible hiked price of the n items (b1, b2..... bn)
5. Calculate the difference between the current and hiked prices for each item i.e. [tex]d_i = b_i - a_i[/tex]
6. Sort the differences in descending order (i.e. from the greatest to the least)
7. Buy items in this order of difference
8. Stop
Explanation:
The algorithm is self-explanatory; however, what it does is that:
It takes a list of the current price of items (say list a)
E.g: [tex]a = [100, 150, 160][/tex]
Then take a list of the hiked price of the items (say list b)
E.g: [tex]b = [110, 180, 165][/tex]
Next, it calculates the difference (d) between corresponding prices [tex]d_i = b_i - a_i[/tex]
[tex]d = [(110 - 100),(180-150),(165-160)][/tex]
[tex]d = [10,30,5][/tex]
Sort the difference from greatest to lowest (as the difference is sorted, lists a and b are also sorted)
[tex]d = [30,10,5][/tex]
[tex]a = [150, 100, 160][/tex]
[tex]b = [180, 110, 165][/tex]
If there is no hike up to item k, the couple would have saved (i = 1 to d[k-1])
Assume k = 3
The couple would have saved for 2 item
[tex]Savings = d[1] + d[2][/tex]
[tex]Savings = 30 +10[/tex]
[tex]Savings = 40[/tex]
The saved amount will then be added to the kth item in list a i.e. a[k](in this case k = 3) in order to buy b[k]
Using the assumed value of k
[tex]a[k] = a[3][/tex]
[tex]a[3] = 160[/tex]
[tex]b[3] = 165[/tex]
Add the saved amount (40) to a[3]
[tex]New\ Amount = 40 + 160[/tex]
[tex]New\ Amount = 200[/tex]
This new amount can then be used to buy b[3] i.e. 165, then they save the change for subsequent items

How does an online discussion group differ from one that is held face-to-face?
There is no need for group roles when holding online meetings.
Online discussion groups do not allow members to develop critical-thinking skills.
Group members are more likely to bond together as a group online than they would when meeting face-to-face.
Facilitating an online conversation may require even more work, so that participants continue engaging with one another online.
Answer: they always will have a different thinkage from others
Explanation:Some people need actual in person learning for better grades it also keeps them from getting distracted easily, they have different brains in everyone in the world everyone thinks, acts and talks in different ways some people dont need in person school because they would rather be online wich are both ok so yes they do bond together online but better in person.
Online discussion group differ from one that is held face-to-face as Group members are more likely to bond together as a group online than they would when meeting face-to-face. Thus, option C is correct.
What is software organization?A system that defines how specific activities, in this case, the software development process, are directed to achieve corporate goals is referred to as an organizational structure. These activities could include putting rules, roles, and responsibilities in place.
There are four basic modes of collaboration, as illustrated by the exhibit "The Four Ways to Collaborate": a closed and authoritarian network (an elite circle), an open and hierarchical connectivity (an innovation mall), an open and flat network (an innovation community), and a shuttered and flat network (a consortium).
Groupware is software that allows a group of people to work together on the same system or application, regardless of where they are. Email, newsgroups, and many more are examples of groupware applications.
Thus, option C is correct.

Lists are an example of a data abstraction.
A data abstraction can often contain different types of elements. It also provides a separation between the abstract properties of a data type (integer, boolean, string) and the concrete details of its representation. Basically, it doesn’t matter that the type are different!
Create an empty list. Append the integer 3, a string of "hello" and a boolean of False into the list. Print out each index individually. Now, remove the number 3 and False from the list.
Finally, print out the list again.
Answer:
Explanation:
The following Python code does exactly as requested. Once the list is created and the elements are added to it, it uses a for loop to print out each element individually. Then once the loop is over it removes the 3 and False elements from the list and creates another for loop to print the remaining element(s) individually again.
my_list = []
my_list.append(3)
my_list.append("hello")
my_list.append(False)
for x in my_list:
print(x)
my_list.remove(3)
my_list.remove(False)
for x in my_list:
print(x)

Write a program that accepts a positive integer N as command-line argument, and outputs True if N is the square of some integer, and False otherwise. Do not use math.sqrt() or similar! Hint: Clearly, all candidates i which may satisfy i2 = N must be at most N (for which "corner case" of N is i equal to N?). Therefore, it is sufficient to check if there exists an i in the range 1 ≤ i ≤ N such that i2 = N. In other words, you want to evaluate the expression (12 == N)or (22 == N)or (32 == N)or ··· or ((N − 1)2 == N) or (N2 == N). Practice goal: A variation of the primality checking program we have seen in class; follows a Boolean accumulation pattern, with logical or.
Answer:
In Python:
N = int(input("Positive integer: "))
if N > 0:
flag = False
for i in range(1,N+1):
if i * i == N:
flag = True
break
print(str(flag))
else:
print("Positive integer only")
Explanation:
N = int(input("Positive integer: "))
If the number is positive
if N > 0:
This initializes a boolean variable to false
flag = False
This iterates from 1 to the input integer
for i in range(1,N+1):
This checks if th number is a square of some integer
if i * i == N:
If yes, flag is set to true
flag = True
The loop is exited
break
This prints either true or false, depending on the result of the loop
print(str(flag))
If otherwise, that the number is not positive
else:
print("Positive integer only")
Add the following method to the Point class: public double distance(Point other) Returns the distance between the current Point object and the given other Point object. The distance between two points is equal to the square root of the sum of the squares of the differences of their x- and y-coordinates. In other words, the distance between two points (x1, y1) and (x2, y2) can be expressed as the square root of (x2 - x1)2 (y2 - y1)2. Two points with the same (x, y) coordinates should return a distance of 0.0.
public class Point {
int x;
int y;
// your code goes here
}
Answer:
public class Point
{
public int x;
public int y;
Point(int x,int y)
{
this.x=x;
this.y=y;
}
public static void main(String[] args)
{
Point p1=new Point(-2,3);
Point p2=new Point(3,-4);
System.out.println("distance:"+distance(p1,p2));
}
private static double distance(Point p1,Point p2)
{
return Math.sqrt(Math.pow(p2.x-p1.x, 2)+Math.pow(p2.y-p1.y, 2));
}
}
Explanation:
The java program defines the Point class and the public method 'distance' to return the total distance between the two quadrants passed to it as arguments (they are both instances of the Point class).

The cash register program will have items. For each item, the name and cost are saved. For a transaction, it will accept any number of items (not known in advance) and any number of payments of different payment types (not known in advance). For each transaction, it calculates the total including a 7% sales tax and keeps prompting for a payment until the total has been paid. It also determines if any change is required. Thus, a transaction is responsible for calculating the amount of money that needs to be paid, accepting money, and generating a receipt. A receipt holds information about a transaction so that it can display how much each item cost, how the transaction was paid for, etc. (see example outputbelow).Payment type includes CASH, DEBIT_CARD, CREDIT_CARDandCHECK. Each payment consists of an amount and payment type
Hints
1. All fields should be private.
2. The PaymentType class should be an enum class with values: CASH, DEBIT_CARD, CREDIT_CARD, CHECK
3. Payment type information should not print the enum directly
4. Use final to store the transaction for each receipt.
5. Output:
A. The values for subtotal, tax, total, and payment information are all aligned. You can achieve this by using the tab character '\t' in your Strings. The item lines do not need to be aligned.
B. Do not worry about only using 2 decimal places. Let Java decide how many decimal places to use.
6. Create a main class to house the main method. In the main method, create some items, a transaction, and display the receipt.
A. Example outputs
Example: Pay everything with one payment

we are writing a program that takes a word and checks how many letters
Answer:
def word_count(word):
return len(word)
a = word_count('scream')
print(a
Explanation:
Using python3:
def word_count(word):
#defines a function named word_count which takes in a single argument which is the word to be counted
return len(word)
#The only thing the function does is to count the number letters in the word.
For instance :
return len(word)
Calling the function and attaching it to the variable named a
Counts the number of letters in scream and assigns the result to a
a = word_count('scream')
print(a)
a gives an output of 6 ; which is the number of letters in scream.
Write a program that calculates the amount of money in a savings account that earns a guaranteed yearly interest rate. The program will accept from the user the account is present value (i.e. what is in the savings account now), the annual interest rate (in a percentage), and the number of years the money will be left in the account (years). The program should display the savings account future value and the number of years the money will be left in the account.
Solution :
# Reading principle amount from user
[tex]$\text{accountPresentValue}$[/tex] = eval([tex]$\text{inpu}t("$[/tex]Enter principle amount: "))
# Reading time duration in number of year from user
years = eval(input("Enter time duration in number of year: "))
# Reading interest rate from user
annualInterestRate = eval(input("Interest rate: "))
# calculating futureValue using user input data
futureValue = accountPresentValue * (1 + annualInterestRate / 100) ** years
# printing calculated futureValue to console
print("Final balance =",futureValue)

A palindrome is a string that is the same when read left to right as when read right to left. Write a program that determines if an arbitrary string is a palindrome. Assume that the string can have blanks, punctuation, capital letters and lower case.
Answer:
In Python:
strng = input("String: ")
revstrng = strng[::-1]
if strng == revstrng:
print("True")
else:
print("False")
Explanation:
This prompts user for string input
strng = input("String: ")
This reverses the string input by the user
revstrng = strng[::-1]
This checks if strings and the reverse string are equal
if strng == revstrng:
Prints True, if yes
print("True")
Prints False, if otherwise
else:
print("False")

In QBasic, create a number guessing challenge. Your program should generate a random number from 1-
100 (inclusive). Let the user guess a number. The program should let the user guess until they get the
correct number. After each input, the program should tell the user whether they guessed the correct
number, or if they guessed too high or too low. While the user is entering guesses, the program should
keep a count of the number of guesses that it takes to get the correct number. After the user guesses
the correct number, the program should congratulate the user and tell them how many guesses it took
them to get the correct number. By the way, if the user chooses carefully, they should be able to guess
the number within 7 tries. But, your program should still let the user keep guessing until they guess the
correct number

g Consider the turning point problem again, but this time you are given a sequence of at least three integers, which consists of a decreasing subsequence followed by an increasing subsequence. Using the divide and conquer technique, develop a recursive algorithm that finds the index of the turning point in the sequence (that is, the point where it transitions from a decreasing subsequence to an increasing subsequence). For example, in the sequence [43 30 16 10 7 8 13 22], the integer 7 is the turning point and its index is equal to 4 (assuming the starting index is 0). So, the algorithm should return 4

The following code is written in Python, it creates a recursive function that takes in a list as a parameter, then compares the first two items in the list if the first is greater, it increases the index by one and calls the function again. This is done until the turning point is found, it then prints out the position of the turning point int the list.
def find_turning_point(list, x=0):
if list[x] > list[x + 1]:
x += 1
return find_turning_point(list, x)
else:
return "The turning point position is: " + str(x)
You can write a function to find Fibonacci numbers using recursion.
How do you find the next number?
add five to the previous number
add one to the previous number
multiply the two previous numbers
add the two previous numbers
Answer:
Add the two previous numbers
Explanation:
A recursive definition of the Fibonacci sequence would look like this, in python:
def fibonacci(n)
if n <= 1:
return n
else:
return(fibonacci(n-1) + fibonacci(n-2))
