很明显也没有看数据范围

数是否有k个数为3的数位！ 贴代码：

#include<bits/stdc++.h>
#define int long long
using namespace std;
signed main()//防止出错！
{
    int n,s,k;
    cin >> n >> k;
    while(n)
    {
        if(n % 10 == 3) s++;
        n = n / 10;
    }
    cout << (s == k?"YES":"NO") << endl;
    return 0;
}

记得要开long long

代码已试无毒：

#include<bits/stdc++.h>
using namespace std;
long long a,k,c,cnt;
int main(){

    cin>>a>>k;
    while(a!=0){
        c=a%10;
        a/=10;
        if(c==3)cnt++;
    }
    if(k==cnt)cout<<"YES";
    else cout<<"NO";

    return 0;
}

求关
