## [Solution] Perfect Permutation solution codechef

Perfect Permutation solution codechef – An index ii in a permutation PP of length NN is said to be good if: PiPi is divisible by ii You are given 22 integers NN and KK. You need to construct a permutation PP of length NN such that exactly KK indices in that permutation are good. If no such permutation exists, output −1−1. If multiple such permutations exist, output any. Perfect Permutation solution codechef The first line contains a … Read more
