先贴我的代码:

/*********************************************************************

*********************************************************************/
#include <bits/stdc++.h>
using namespace std;
#define int long long

namespace sio {
	int inn() {
		int k = 0;
		bool ok = 0;
		char ch = getchar();
		for (; !(ch <= '9' && ch >= '0');) {
			if (ch == '-') {
				ok ^= 1;
			}
			ch = getchar();
		}
		for (; (ch <= '9' && ch >= '0');) {
			k = (k << 1) + (k << 3) + (ch ^ 48);
			ch = getchar();
		}
		return ok ? -k : k;
	}
	struct In {
		In operator >>(int &a) {
			a = inn();
			return {};
		}
	} in;
}
using namespace sio;

struct node {
	int m, p, mm, pp, k;
} a[104];
int f[1000][1000];
int l[1000][1000];

signed main() {
	/*
		freopen("power.in", "r", stdin);
		freopen("power.out", "w", stdout);*/
	int n;
	in >> n;
	for (int i = 1; i <= n; i++) {
		in >> a[i].mm >> a[i].pp  >> a[i].m >> a[i].p >> a[i].k;
	}
	int ans = 0;
	for (int i = 0; i <= 800; i++) {
		for (int j = 0; j <= 800; j++) {
			if (i < 400 || j < 400) {
				f[i][j] = -1e9;
			}
		}
	}
	for (int i = 1; i <= n; i++) {
		for (int jj = 400; jj >= -400; jj--) {
			for (int kk = 400; kk >= -400; kk--) {
				int j = jj + 400, k = kk + 400;
				l[j][k] = max(f[j][k], f[j + a[i].mm][k + a[i].pp]);
				if (j >= a[i].m && k >= a[i].p) {
					l[j][k] = max(l[j][k], f[j - a[i].m][k - a[i].p] + a[i].k);
				}
			}
		}
		for (int j = 800; j >= 0; j--) {
			for (int k = 800; k >= 0; k--) {
				f[j][k] = l[j][k];
			}
		}
	}
	cout << f[400][400] << "\n";
	return 0;
}

然后是测试点3输入:

3
1 7 7 8 6
9 9 7 3 5

注意到少了一行
