if n = 2,
2T (n/2) +n if n = 2k, for k > 1
is T(n) = n lgn.

We can express insertion sort as a recursive procedure as follows. In order to sort
A[1..n], we recursively sort A[1. . n − 1] and then insert A[n] into the sorted array
A[1 . . n − 1]. Write a recurrence for the running time of this recursive version of
insertion sort.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F032de2f6-d35c-4a3a-a9a2-daefbabd8c32%2Fba5b5277-78c3-4108-913e-c4e66ae5f6f7%2F6zbtnci_processed.png&w=3840&q=75)
