题目大意：CRB生日，妈妈要给他买礼物，妈妈有M元钱，这家店有N种礼物，因为店长和妈妈是熟人，所以若第i种礼物买x件的话，店长会给妈妈Ai*x+Bi颗糖果，现给出每种礼物的单价、Ai值与Bi值，问妈妈最多能拿到多少颗糖果。

解题思路：01背包 + 完全背包

#include <cstdio>
#include <algorithm>
using namespace std;

int main() {
int T;
scanf("%d", &T);
while (T--) {
int N, M, DP[2010] = {0};
scanf("%d%d", &M, &N);
for (int r = 1; r <= N; r++) {
int W, A, B;
scanf("%d%d%d", &W, &A, &B);
for (int i = M; i >= W; i--)
DP[i] = max(DP[i], DP[i-W] + A + B);
for (int i = W; i <= M; i++)
DP[i] = max(DP[i], DP[i-W] + A);
}
printf("%d\n", DP[M]);
}
return 0;
}
