Shekhar is a bomb defusal specialist. He once encountered a bomb that can be defused only by a secret code. He is given a number N and a number K. And he is also given permutation of first N natural numbers . The defusal code is the largest permutation possible by doing exactly K swaps among a pair of the given permutation.
