#include <iostream>
#include <cstring>
#include <algorithm>
using namespace std;
bool a[4][20];
int num[] = { 2, 3, 5, 6 };
void dfs(int u, int x) {
a[u][x] = true;
if (u == 3) return;
for (int i = 0; i < 4; i++) {
dfs(u + 1, x + num[i]);
}
}
int main() {
int s, b;
scanf("%d%d", &s, &b);
if (b > 18 || s > 12) {
puts("NO");
return 0;
}
dfs(0, 0);
if (s == 0) {
if (a[3][b]) puts("YES");
else puts("NO");
} else if (s == 1 || s == 4) {
if (a[2][b]) puts("YES");
else puts("NO");
} else if (s == 2 || s == 5 || s == 8) {
if (a[1][b]) puts("YES");
else puts("NO");
} else if (s == 3 || s == 12 || s == 9 || s == 6) {

else puts("NO");
} else puts("NO");
return 0;
}
这程序好像有点Bug，我给组数据试试？
