WebAug 25, 2016 · $\begingroup$ I'll sketch an algorithm which generates all the possibilities by backtracking. In a sense the counting problem is more difficult than the generating problem, in that great effort is required to produce a single number (while the generating problem may efficiently go from one sub-multiset to the next). $\endgroup$ – WebThe following recursive algorithm (implemented in C) is based on the above idea. generate(s;r) (s for \start", r for \remaining") generates all r-combinations of elements a[s] to a[n 1] over indices (k r) to (k 1) of c. The initial call has s = 0 and r = k. print() prints the combination currently in c. #define n 10
