what is the perpose of the boolean variable swaps in this buble sort algorithm
Answers
Answer:
“Bubble Up” algorithm will move largest
value to its correct location (to the
right/end of array)
• Repeat “Bubble Up” until all elements are
correctly placed:
– Maximum of N-1 times
– Can finish early if no swapping occurs
• We reduce the number of elements we
compare each time one is correctly placed
The method removeDupes is intended to remove duplicates from array a, returning n, the number of elements in a after duplicates have been removed. For example, if array a has the values {4, 7, 11, 4, 9, 5, 11, 7, 3, 5} before removeDupes is called, then after duplicates are removed, a will be {4, 7, 11, 5, 9, 3} and 6 will be returned.Consider the following three implementations of RemoveDupes.

When it comes to paying bills at restaurants, Wallace always leaves a 15% tip based on the pretax price. However, Wallace is tired of computing tips every time, please construct a function total_bill, which takes a numerical argument pretax and returns the total bill by 1) calculating the tip, 2) the after-tax price, and 3) adding the tip to the after-tax price. Assume the sale tax is 9%. Below is how the function would be used:

Consider the following code segment.
int a = 0;
int b = 3;
while ((b != 0) && ((a / b) >= 0)
{
a = a + 2;
b = b - 1;
}
What are the values of a and b after the while loop completes its execution?
a = 4, b = 1
a = 0, b = 3
a = 6, b = 0
a = 8, b = -1
Answers
Answer:
a = 6, b = 0
Explanation:
The loop ran 3 times before b == 0. The statement "while ((b != 0)" is essentially saying: 'While b is not equal to 0, do what's in my loop'. Same general thing with "&& ((a / b) >= 0)". The "&&" is specifying that there should be another loop condition. The final part of the while loop states: 'as long as a ÷ b is greater than 0, do what's in my loop'. If all of these conditions are met, the loop will run. It will continue to run until at least one of the conditions are not met.

How do most benchmark tests measure the performance of a graphic card
Answers
Answer:
Using Frame Rate
Explanation:
Most benchmark tests measure the performance of a graphic card by using "Frame Rate"
This is because using Frame Rate assesses and then measures the number of images a GPU (graphic processing unit) can render and at the same time the number of images that are being shown on a monitor or screen per second.
Hence, in this case, the correct answer is "Frame Rate"
