Question: The inner loop of the insertion sort algorithm uses a linear search to scan backward through the so far sorted sub-array A[0.. i 1] in

The inner loop of the insertion sort algorithm uses a linear search to scan backward through the so far sorted sub-array A[0.. i 1] in order to insert A[i] in its correct position.

a. Modify the insertion sort algorithm using a binary search (instead of linear search) to find the insertion point of A[i]. Write your solution in pseudocode.

b. Does this modification improve the overall worst-case running time of insertion sort to (nlgn)? Explain your answer.
