Write a recursive function that has an argument that is an array of characters and two arguments that are bounds on array indexes. The function should reverse the order of those entries in the array whose indexes are between the two bounds. For example, if the array is a[0]
Answer:
The function is as follows:
void revArray(char arr[], unsigned int low, unsigned int high) {
if (low >= high){
return; }
swap(arr[low], arr[high]);
revArray(arr, low + 1, high - 1); }
Explanation:
This declares the function. It receives a char array and the lower and upper bounds to be reversed
void revArray(char arr[], unsigned int low, unsigned int high) {
This is the base case of the recursion (lower bound greater than or equal to the upper bound).
if (low >= high){
return; }
This swaps alternate array elements
swap(arr[low], arr[high]);
This calls the function for another swap operation
revArray(arr, low + 1, high - 1); }

Hello all i need help on my next task on Procedural Programming, ive tried to understand many times but i keep getting misled, im a beginner.
Objective
Name: Dot product
Description:
Write a procedure, called dot_product which calculates in the variable ps, the dot(scalar) product of v1 and v2 (v1 and v2 are vectors of IR)
Write an algorithm which determines, for n pairs of given vectors, whether two vectors of given IR are orthogonal, by calling the procedure defined in the previous question. The dot product of two orthogonal vectors is zero.
Modify the previous algorithm if you use a dot_product function instead of a procedure.
Instructions:
Use array for presenting the vector.
Use nested loop (a loop inside another)
Use different types of passing parameters
Answer:

Explanation:
hope its hlp you to understand to find the answer
The `dot_product` is defined as a function, and it returns the dot product value instead of storing it in a variable.
How did we realize this dot product?Let's break down the task into various steps and work on them one by one.
1. Implementing the dot_product procedure: To calculate the dot product of two vectors, you need to multiply the corresponding elements of the vectors and sum them up. Here's an example implementation of the dot_product procedure in a procedural programming language:
procedure dot_product(v1, v2):
n = length(v1) # Assuming both vectors have the same length
ps = 0 # Initialize the dot product variable to zero
for i = 1 to n:
ps = ps + v1[i] * v2[i] # Multiply corresponding elements and add to the dot product variable
return ps
In this procedure, `v1` and `v2` are the input vectors, and `ps` is the dot product result.
2. Checking if vectors are orthogonal: Now, let's write an algorithm to determine whether two vectors are orthogonal by calling the `dot_product` procedure. We'll use a nested loop to iterate over pairs of vectors.
algorithm check_orthogonal_vectors(vectors):
n = length(vectors) # Number of vector pairs
for i = 1 to n:
v1 = vectors[i][1] # First vector in the pair
v2 = vectors[i][2] # Second vector in the pair
ps = dot_product(v1, v2) # Call the dot_product procedure
if ps == 0:
output "The vectors", v1, "and", v2, "are orthogonal."
else:
output "The vectors", v1, "and", v2, "are not orthogonal."
In this algorithm, `vectors` is an array containing pairs of vectors. Each pair should be a 2D array where the first element represents the first vector and the second element represents the second vector.
Modifying the algorithm using a dot_product function: If you want to use a function instead of a procedure for calculating the dot product, here's how you can modify the previous algorithm:
function dot_product(v1, v2):
n = length(v1) # Assuming both vectors have the same length
ps = 0 # Initialize the dot product variable to zero
for i = 1 to n:
ps = ps + v1[i] * v2[i] # Multiply corresponding elements and add to the dot product variable
return ps
algorithm check_orthogonal_vectors(vectors):
n = length(vectors) # Number of vector pairs
for i = 1 to n:
v1 = vectors[i][1] # First vector in the pair
v2 = vectors[i][2] # Second vector in the pair
ps = dot_product(v1, v2) # Call the dot_product function
if ps == 0:
output "The vectors", v1, "and", v2, "are orthogonal."
else:
output "The vectors", v1, "and", v2, "are not orthogonal."
In this modified version, the `dot_product` is defined as a function, and it returns the dot product value instead of storing it in a variable.

Write a method called lexLargest that takes a string object argument containing some text. Your method should return the lexicographical largest word in the String object (that is, the one that would appear latest in the dictionary).
public static String lexLargest(String text){
//split the text based on whitespace into individual strings
//store in an array called words
String[] words = text.split("\\s");
//create and initialize a temporary variable
int temp = 0;
//loop through the words array and start comparing
for(int i = 0; i < words.length; i++){
//By ignoring case,
//check if a word at the given index i,
//is lexicographically greater than the one specified by
//the temp variable.
if(words[i].compareToIgnoreCase(words[temp]) > 0){
//if it is, change the value of the temp variable to the index i
temp = i;
}
}
//return the word given by the index specified in the temp
// variable
return words[temp];
}
Sample Output:If the text is "This is my name again", output will be This
If the text is "My test", output will be test
Explanation:
The code above has been written in Java. It contains comments explaining the code. Sample outputs have also been given.
However, it is worth to note the method that does the actual computation for the lexicographical arrangement. The method is compareToIgnoreCase().
This method, ignoring their cases, compares two strings.
It returns 0 if the first string and the second string are equal.
It returns a positive number if the first string is greater than the second string.
It returns a negative number if the first string is less than the second string.

hello! can someone write a c++ program for this problem
Problema 2018.3.2 - Cheated dice
Costica is on vacation and his parents sent him to the country. There he gets terribly bored and looking through his grandfather's closet, he came across a bag full of dice. Having no one to play dice with, but it seemed to him that some of the dice were heavier than the others, Costica chose a dice and started to test it by throwing it with him and noting how many times each face fell. He then tries to figure out whether the dice are rolled or not, considering that the difference between the maximum number of appearances of one face and the minimum number of occurrences (of any other face) should not exceed 10% of the total number of throws.
Requirement
Given a number N of dice rolls and then N natural numbers in the range [1: 6] representing the numbers obtained on the rolls, determine whether the dice is tricked according to the above condition.
Input data
From the input (stdin stream) on the first line reads the natural number N, representing the number of rolls. On the following N lines there is a natural number in the range [1: 6] representing the numbers obtained on throws.
Output data
At the output (stdout stream) a single number will be displayed, 0 or 1, 0 if the dice are normal, and 1 if it is cheated.
ATTENTION to the requirement of the problem: the results must be displayed EXACTLY in the way indicated! In other words, nothing will be displayed on the standard output stream in addition to the problem requirement; as a result of the automatic evaluation, any additional character displayed, or a display different from the one indicated, will lead to an erroneous result and therefore to the qualification "Rejected".
Restrictions and clarifications
1. 10 ≤ N ≤ 100
2. Caution: Depending on the programming language chosen, the file containing the code must have one of the extensions .c, .cpp, .java, or .m. The web editor will not automatically add these extensions and their absence makes it impossible to compile the program!
3. Attention: The source file must be named by the candidate as: . where name is the last name of the candidate and the extension (ext) is the one chosen according to the previous point. Beware of Java language restrictions on class name and file name!

Write a program called nearest_multiple.py that asks the user to input a number (here I will call it num) and a strictly positive integer (here I will call it mult) and prints as output the closest integer to num that is a multiple of mult
Answer:
The program is as follows:
num = float(input("Enter a decimal (float): "))
mult = int(input("Enter a positive whole (int): "))
small = (num // mult) * mult
big = small + mult
print(num,"rounded to the nearest multiple of ",mult,"is",end=" ")
print(big if num - small > big - num else small)
Explanation:
This gets input for num
num = float(input("Enter a decimal (float): "))
This gets input for mult
mult = int(input("Enter a positive whole (int): "))
This calculates the smaller multiple
small = (num // mult) * mult
This calculates the larger multiple
big = small + mult
This prints the output header
print(num,"rounded to the nearest multiple of ",mult,"is",end=" ")
This prints small if small is closer to num, else it prints big
print(big if num - small > big - num else small)

Given a member function named set_age() with a parameter named age in a class named Employee, what code would you use within the function to set the value of the corresponding data member if the data member has the same name as the parameter
Answer:
Explanation:
This would be considered a setter method. In most languages the parameter of the setter method is the same as the variable that we are passing the value to. Therefore, within the function you need to call the instance variable and make it equal to the parameter being passed. It seems that from the function name this is being written in python. Therefore, the following python code will show you an example of the Employee class and the set_age() method.
class Employee:
age = 0
def __init__(self):
pass
def set_age(self, age):
self.age = age
As you can see in the above code the instance age variable is targeted using the self keyword in Python and is passed the parameter age to the instance variable.
What will be the output of the following JavaScript code? functioncomparison() { int number=10; if(number= = ="10") return true; else return false; } Single choice. (0.5 Points) True false runtime error compilation error
Answer:
(b) false
Explanation:
Given
The above code
Required
The expected output
First, variable number is declared as integer and then initialized with 10
Next, the === compares the integer 10 with string "10"
10 and "10" are different type and === will return true if the compared values and/or variables are of the same type.
Since 10 and "10" are different, the expected output is false
The output of the following JavaScript code is false.
Let's write the code appropriately,
functioncomparison() {
int number = 10;
if (number= = ="10")
return true;
else
return false;
}
A function functioncomparison() is declared.
Then the integer number is assigned as 10.
The conditional "if" says if the string 10 is equals to the integer number 10.
The triple equals signs(===)check for the type and the actual value.
The string "10" and integer 10 are not the same type. "10" is a string and 10 is an integer.
Therefore, the output of the code will be false.

Suppose the CashRegister needs to support a method void undo() that undoes the addition of the preceding item. This enables a cashier to quickly undo a mistake. What instance variables should you add to the CashRegister class to support this modification
Answer:
previousAddition instance variable
Explanation:
In order to accomplish this you would need to add a previousAddition instance variable. In this variable you would need to save the amount that was added at the end of the process. Therefore, if a mistake were to occur you can simply call the previousAddition variable which would have that amount and subtract it from the total. This would quickly reverse the mistake, and can be easily called from the undo() method.
Write a 3-4 page paper (500-800 words) about your project that explains your project, the type of conditioning you used, and the methods and procedures used to execute your project. You should explain the process of shaping the behavior and utilize any or all appropriate vocabulary. Finally, include a discussion of the results and an analysis of recommendations for improvement or future changes.
Answer:
Following are the responses to the given question:
Explanation:
I have decided to take up my project as a change in my behavior of not working out and exercising on daily basis. To execute this project, I decided to use ‘Operant conditioning’ to be able to complete it successfully. The reason for choosing this as my project is to be able to change my unhealthy behavior of not exercising daily, which is now having an impact on my weight as well as on my mind.
Operant Conditioning is also known as instrumental conditioning was used by the behaviorist B.F Skinner. Through operant conditioning, Skinner explained how we adapt to several learned behaviors in our everyday life. Its idea of such conditioning would be that the acts that accompany reinforcement will most likely occur in the future.
They may call it a punishment for actions and retribution. A relationship is formed between that action as well as its consequences. I began my project with an order of a watch to keep track of my daily workout and even downloaded a phone-based software to track my calorie each day. The concept behind it was to understand my everyday work and my calorie consumption because these variables inspire me to choose more to achieve my aim to practice and maintain my weight safely.
So, to find any way to miss it I did the routine calendar. We also made a small and comprehensive strategy for the first few weeks such as early awakening and 10 minutes getting warmed up. I concentrated on the operating conditioning function and reaction. I've been honored by enjoying my important topics for one hour every week that I finished my practice according to my planned routine. I wanted and award myself quarterly rewards in addition to daily rewards. When the goal of a daily exercise is also achieved, I decided to go out to my favorite coffee just at end of November.
It's not a matter of giving one of my favorite stuff to my cousins to affirm my everyday life except for one year within a week (except when I'm unwell). The fear of missing one of my items that I'd always agreed only at beginning of the week prevented me from achieving my target of exercise every day and made me very content to go to my favorite coffee shop. It made it more motivating for someone like me to proceed with the positive and negative reinforcement of doing my everyday exercise routine. I also get used to my fresh and safe routine every day, but also the results are impressive.
Even though I don't feel about rewarding myself with something that I like, I am very much happy because of the positive result which I have a fit body and maintain a healthy lifestyle. Those who removed my daily positive and negative exercise reinforcements, as well as the monthly incentive, could not be required in the future. Moreover, I can work on a closer look for 6 abs.

Write a function that displays the character that appears most frequently in the string. If several characters have the same highest frequency, displays the first character with that frequency. Note that you must use dictionary to count the frequency of each letter in the input string. NO credit will be given without using dictionary in your program
Answer:
The function is as follows:
def getMode(str):
occurrence = [0] * 256
dict = {}
for i in str:
occurrence[ord(i)]+=1;
dict[i] = occurrence[ord(i)]
highest = max(dict, key=dict.get)
print(highest)
Explanation:
This defines the function
def getMode(str):
This initializes the occurrence list to 0
occurrence = [0] * 256
This creates an empty dictionary
dict = {}
This iterates through the input string
for i in str:
This counts the occurrence of each string
occurrence[ord(i)]+=1;
The string and its occurrence are then appended to the dictionary
dict[i] = occurrence[ord(i)]
This gets the key with the highest value (i.e. the mode)
highest = max(dict, key=dict.get)
This prints the key
print(highest)

HTML is an acronym for hypertext markup language and it is a standard programming language which is used for designing, developing and creating web pages.
Generally, all HTML documents are divided into two (2) main parts; body and head. The head contains information such as version of HTML, title of a page, metadata, link to custom favicons and CSS etc. The body of the HTML document contains the contents or informations that a web page displays.
Basically, the purpose of the property, transition-timing-function is that It changes the speed at different stages of the transition. Thus, it states the values between the beginning and ending of a transition are calculated over its duration.
