请大佬帮忙看看这段代码能AC吗?(C语言,dfs )#include int N;int M;int K;int Q[25] = {0};int dfs(int len) { int f = 0; if (len == N + 1) return 1; if (Q[len] == 0 && len Q[len] = -1; f = dfs(len + 1) + dfs(len + 2) + dfs(len + 3); Q[len] = 0; } else if (Q[len] == 1) { if (M > 1) { M--; Q[len] = 0; f = dfs(len); Q[len] = 1; M++; } else return 0; } return f;}int main() { int temp = 0; scanf("%d %d %d", &M, &N, &K); for (int i = 0; i scanf("%d", &temp); Q[temp] = 1; } printf("%d", dfs(0)); return 0;}
