(2 <= N,K <= 8) and an array consisting of N distinct elements; in one move you can pick a block of K elements in the array and reverse the order, for example: if N = 5 and K = 3 and the array is [4 5 1 2 3], in one move you can make the array [1 5 4 2 3]...
Find i, such that ai is the smallest element of array a among index 1 to n. Then if you reverse a1 to ai, you have the smallest element of a at a1. Again, find the smallest among a2 to an and reverse a2 to ai to bring the 2nd smallest to the 2nd position... and so on.....
