( 8484 ) D Almost Identity Permutations PROGRAMMING combinatorics dp math 1600

B"A permutation p of size n is an array such that every integer from 1 to n occurs exactly once in this array. Let's call a permutation an almost identity permutation iff there exist at least n xe2 x80 x89- xe2 x80 x89k indices i (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89i xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n) such that pi xe2 x80 x89= xe2 x80 x89i. Your task is to count the number of almost identity permutations for given numbers n and k. The first line contains two integers n and k (4 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x891000, 1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89k xe2 x80 x89 xe2 x89 xa4 xe2 x80 x894). Print the number of almost identity permutations for given n and k. "...
