The outer for loop runs n times.
If if statement is executed insertion sort takes more time than quick in worst case i.e. O(n^2)
The else part has complexity O(n^2)logn
Thus the whole worst case complexity will be
O(n^3logn)

(C++ program )Write a function that accepts an int array and the array’s size as arguments. The function should create a new array that is one element larger than the argument array. The first element of the new array should be set to 0. Element 0 of the argument array should be copied to the element 1 of the new array. Element 1 of the argument array should be copied to element 2 of the new array, and so forth....
