@duaneryan 1 < n \le 10^{15} 所以要开 long long

by Ravener @ 2024-03-25 19:27:34

要开long long
其实也不是不可以用string

@duaneryan

#include<bits/stdc++.h>
typedef long long ll;
using namespace std;
ll m,k,sumn=0;

int main()
{
    cin>>m>>k;
    while(m>=1)
    {
        if(m%10==3)
        {
            sumn++;
        }
        m/=10;
    }
    if(sumn==k)
    {
        cout<<"YES";
    }
    else
    {
        cout<<"NO";
    }

    return 0;
}

拿去吧

@lyq123bc ```cpp

ll m,k,sumn=0;

这里的ll是long long的缩写吗

@zhouzihang1 谢谢大佬（喜）

@Ravener 真的诶，谢谢（牢大）大佬

@duaneryan

typedef long long ll;

这句话的意思是把所有的 ll 看成 long long 编译
