Answer:
EventHandler
Explanation:
In order to do this the programmer needs to use the EventHandler class. This class allows the computer to listen for certain user actions such as pressing a button. Using this on a button would then allow the programmer to specify what they want to happen when the user clicks the button or performs a certain action. For example, in this scenario, the programmer would program an EventHandler so that when the button is clicked it saves the input to a variable and changes the input field to the next option.

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.

consider a memory system with a memory access time of 150 ns and a cache access time of 20ns. If the effective access time is 20% greater than the cache access time, what is the hit ratio H g
Answer:
H = 0.7333333
Explanation:
Given that:
The memory access time ([tex]T_m[/tex]) = 150 ns
The cache access time [tex](T_c)[/tex] = 20 ns
Effective access time [tex](T_e)[/tex] = 20% > [tex](T_c)[/tex]
Then, it implies that:
= [tex](T_c)[/tex] + 20% of
=[tex](T_c)[/tex](1+20%)
=[tex](T_c)[/tex](1+ 0.2)
= 20ns × 1.2
= 24ns
To determine the hit ratio H;
Using the formula:
[tex]T_e = T_c \times H+(1-H) \times (T_c + T_m) \\ \\ T_e = HT_c + T_c + T_m -HT_c -HT_m \\ \\ T_e = T_c +T_m - HT_m \\ \\ T_c -T_e = T_m (H-1) \\ \\ H-1 = \dfrac{T_c -T_e}{T_m} \\ \\ H = 1+ (\dfrac{T_c -T_e}{T_m})--- (1)[/tex]
Replacing the values; we have:
[tex]T_c - T_e = 20ns - 24 ns \\ \\ T_c - T_e = -4 ns \\ \\ \dfrac{T_c - T_e }{T_m} = \dfrac{-4 ns}{150} \\ \\ \dfrac{T_c - T_e }{T_m} = -0.02666667[/tex]
From (1)
[tex]H = 1+ (-0.2666667) \\ \\ H = 1 - 0.2666667 \\ \\ \mathbf{H = 0.7333333}[/tex]

Explanation:
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); }
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.
Second Largest, Second Smallest Write a program second.cpp that takes in a sequence of integers, and prints the second largest number and the second smallest number. Note that in the case of repeated numbers, we really mean the second largest and smallest out of the distinct numbers (as seen in the examples below). You may only use the headers: and . Please have the output formatted exactly like the following examples: (the red is user input) Enter integers (Q to quit): 1 2 1 8 8 9 Q Second largest: 8 Second smallest: 2 Enter integers (Q to quit): -7 -101 0 -2 17 Q Second largest: 0 Second smallest: -7

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.

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!

In our discussion of Linear-Time Sorting, we talked about an algorithm called radix sort, which does successive iterations of another algorithm called counting sort, with each of those iterations focused on one digit (e.g., sorting by the last digit and ignoring all the others, sorting by the second-to-last digit and ignoring all the others, or whatever). Suppose that you replaced counting sort, at each step, with a hypothetical algorithm that was faster than counting sort but was not stable. If you did, would you expect radix sort to still come up with a correct result
Answer:
Explanation:
Suppose we use some other sorting technique as the subroutine for radix sort to sort the digit, it will be unstable. The final outcome will not be accurate and correct. This is due to the fact that Unstable sort does not retain the order for equal components, thus whatever sorting was done before for lower significant bits might be screwed up by the next significant bit at that level that possesses the same value.
Consider the following scenario:
[431, 135, 132]
⇒ [431,132,135] (The least significant bit is used in the first step of sorting.)
⇒ [132, 431, 135] (Because the sorting algorithm was not reliable, the second level of sorting screwed up the preceding sorting.)
As a result, we will never receive an accurate and coorect outcome in this scenario.

political freedom and religious freedom
protecting criminals’ personal emails
knowing how personal data are collected and used
please answer asap as well as the others i posted
Answer:
knowing how personal data are collected and used.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to effectively and efficiently create, store, modify, retrieve, centralize and manage data or informations in a database. Thus, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Generally, a database management system (DBMS) acts as an intermediary between the physical data files stored on a computer system and any software application or program.
Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, etc.
Basically, the two (2) essential privacy concerns in the field of cybersecurity are knowing how personal data are collected and essentially how they're used by the beneficiaries or end users.
This ultimately implies that, the medium (channel) and methods through which personal data are collected or obtained plays a huge role in determining how secured or unsecured a user's data are. Also, the manner in which a person's personal data is used should be well defined.

g 4-6 you've been given the network 200.5.0.0 /24 and need to subnet it using vlsm as follows: bldg 1 30 hosts bldg 2 10 hosts bldg 3 10 hosts bldg 4 4 hosts what will be the network address for bldg 3
Answer:
The answer is "200.5.0.0 32/28".
Explanation:
The requirement of the Bldg is =30.
The number of the host bits which is needed = 5
Therefore the subnet mask will be =/27
for bldg 3 netmask could be= /28
and when the /28 after that the last octet will be= 00100000.
00100000 converting value into a decimal value that is = 32.
therefore the correct value is 200.5.0.32 /28.
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)
