Multichoosing
Web1 mar. 2016 · The number of k-element multisets whose elements all belong to [n] We have then a 1 + a 2 + ⋯ + a n = k and each a i is a non-negative integer. The set of solutions to the above equation are in direct bijection with the k -element multisets of [ n] using an obvious bijection: ( a 1, a 2, …, a n) ↔ { a 1 ⋅ 1, a 2 ⋅ 2, …, a n ⋅ n ... WebIs there any trick to quickly get the sequence of inner elements given their corresponding sum? (e.g. given the sums 5 4 3, results in 2, 3; 3, 1; 1, 2). Previously without such method, my implementation uses permutations to generate inner sequence which is very slow.
