@zhenshijuruo 《《含有k个三的》》

by zhenshijuruo @ 2024-09-15 14:25:25

@hexuchen 呃是指把这个数看成字符串然后看字符串里有没有k个3的意思吗

by scratch_szc @ 2024-09-15 14:27:46

萌新求助！为什么40分（滑稽）

#include<bits/stdc++.h>
using namespace std;
int main(){
    string n;
    int p;
    int t;
    cin>>n>>p;
    for(int i=0;i<n.size();i++)if(n[i]==3+'0')t++;
    if(t==p)cout<<"YES";
    else cout<<"NO";
}
