Appended below is the code for Selection Sort. You really do not have to understand the details of the code. If this algorithm takes 4 seconds to sort an array of 8 elements. How much time in seconds will the same code take to sort an array of 24 elements?

12 seconds.

Step-by-step explanation:

Let t represent time taken by code to sort an array of 24 elements.

We have been given that an algorithm takes 4 seconds to sort an array of 8 elements. We are asked to find the time it will take for same code to sort an array of 24 elements.

We will use proportions to solve our given problem.    

Therefore, it will take 12 seconds for the same code to sort an array of 24 elements.

To find the slope you have to use the equation Y2-Y1
