读题眼瞎，判断了除法的代码也过了。

#include <cstdio>
int main()
{
    long long a, b, c, d;
    scanf("%lld %lld %lld %lld", &a, &b, &c, &d);
    if ((a + b) + c == d)
    {
        printf("Yes\n");
    }
    else if ((a + b) - c == d)
    {
        printf("Yes\n");
    }
    else if ((a + b) / c == d)
    {
        printf("Yes\n");
    }
    else if ((a + b) * c == d)
    {
        printf("Yes\n");
    }
    else if ((a - b) + c == d)
    {
        printf("Yes\n");
    }
    else if ((a - b) - c == d)
    {
        printf("Yes\n");
    }
    else if ((a - b) / c == d)
    {
        printf("Yes\n");
    }
    else if ((a - b) * c == d)
    {
        printf("Yes\n");
    }
    else if ((a * b) + c == d)
    {
        printf("Yes\n");
    }
    else if ((a * b) - c == d)
    {
        printf("Yes\n");
    }
    else if ((a * b) / c == d)
    {
        printf("Yes\n");
    }
    else if ((a * b) * c == d)
    {
        printf("Yes\n");
    }
    else if ((a / b) + c == d)
    {
        printf("Yes\n");
    }
    else if ((a / b) - c == d)
    {
        printf("Yes\n");
    }
    else if ((a / b) / c == d)
    {
        printf("Yes\n");
    }
    else if ((a / b) * c == d)
    {
        printf("Yes\n");
    }
    else
    {
        printf("No\n");
    }
    return 0;
}
