In C++.

Transcribed Image Text:Sort an array of 10,000 elements using the quick sort algorithm as follows:
a. Sort the array using the pivot as the middle element of the array.
b. Sort the array using the pivot as the median of the first, last, and middle elements of the array.
c. Sort the array using the pivot as the middle element of the array. However, when the size of any sublist reduces to less than 20, sort the sublist using an insertion sort.
d. Sort the array using the pivot as the median of the first, last, and middle elements of the array. When the size of any sublist reduces to less than 20, sort the sublist using an insertion sort.
e. Calculate and print the CPU time for each of the preceding four steps.
To find the current CPU time, declare a variable, say, x, of type `clock_t`. The statement `x = clock();` stores the current CPU time in x. You can check the CPU time before and after a particular phase of a program. Then, to find the CPU time for that particular phase of the program, subtract the before time from the after time. Moreover, you must include the header file `ctime` to use the data type `clock_t` and the function `clock`. Use a random number generator to initially fill the array.
