题目描述 输入一个数字n(2 <= n <= 1000)，计算将n拆分为m(1 <= m <= 50)个素数之和的方案数ans。①处应填写

#include <bits/stdc++.h>
using namespace std;
vector < int > p;
bool vis[1005];
int dp[205][55][1005];
int main() {
    p.push back(-l);

    for (inti = 2; i <= 1000; i++) {

        if (!vis[i]) {

            ①;

            for (intj = i; j <= 1000; j += i) vis[j] = 1;

            int n， mi

            scanf("%d%d"， & n， & m);

            ②;

                for (int i = l; i < p.size(); i++) {

                    for (inti = 0; j <= m; j++) {

                        for (int k = 0; k <= n; k++) {

                            if (j && k >= p[i]) :

                          			③;

                                else

                                    ④;

                        }

                    }

                }

            printf("号d\n"⑤);

            return 0;

         }
