注意读题：

题目要求是sum == k

所以代码如下：

#include<bits/stdc++.h>
using namespace std;
int main(){
    unsigned long long n, k, sum = 0;
    cin >> n >> k;
    while (n != 0) {
        if(n % 10 == 3) {
            sum++;
        }
        n/=10;
    }
    puts(sum==k?"YES":"NO"); // 将“>= ”改为 “== ” 
    return 0;
}
