最准题解

#include <iostream>
using namespace std;

int main() {
    int m, k;
    cin >> m >> k;
    if (m % 19 != 0) {
        cout << "NO";
        return 0;
    }
    int count = 0;
    int temp = m; 
    while (temp > 0) {
        int digit = temp % 10;
        if (digit == 3) {
            count++;
        }
        temp = temp / 10;
    }
    if (count == k) {
        cout << "YES";
    } else {
        cout << "NO";
    }

    return 0;
}

绝对正确！！！
