1. Write a function, removeAt, that takes three parameters: an array of integers, the number of elements in the array, and an integer (say, index). The function should delete the array element indicated by index. If index is out of range or the array is empty, output an appropriate message. (Note that after deleting the element, the number of elements in the array is reduced by 1.) Assume that the array is unsorted. 2.Write a program that creates three identical arrays, list1, list2, and list3 of 5000 elements. The program then sorts list1 using bubble sort, list2 using selection sort, and list3 using insertion sort and outputs the number of comparisons and item assignments made by each sorting algorithm.
