Let dp[i] be and gcd be the number of plans for i. Then we can find that dp[i] = (k/i)^n, but there is a number of schemes where gcd is a multiple of i, and then subtract the multiple. Finally, the contribution of gcd to i is: i*dp[i] AC code:

Webn of zero-sum-free d-tuples in Zd n. We begin with an observation. Fact 1. Let dand nbe positive integers. Then d n=0 if and only if d≥n. This follows from the well-known fact that a 1;:::;a nof (not necessarily distinct) elements of Z ncontains a subsequence whose sum is 0 ∈Z n, and that (1;1; ;1) is a zero-sum-free d-tuple in Zd n ...
