标Turtle and Equations题解

思路

枚举 把所有方法都枚举出来就好了。

解题方法

没啥可说的，把所有情况都写出来

Code

#include <bits/stdc++.h>
using namespace std;

int main(){
    int a, b, c, d;
    cin >> a >> b >> c >> d;

    if ((a + b) + c == d) cout << "Yes\n";
    else if((a + b) - c == d) cout << "Yes\n";
    else if((a + b) * c == d) cout << "Yes\n";
    else if((a - b) + c == d) cout << "Yes\n";
    else if((a - b) - c == d) cout << "Yes\n";
    else if((a - b) * c == d) cout << "Yes\n";
    else if((a * b) + c == d) cout << "Yes\n";
    else if((a * b) - c == d) cout << "Yes\n";
    else if((a * b) * c == d) cout << "Yes\n";
    else cout << "No\n";

    return 0;
}
