@linyuqikimi 输出要在循环里特判

@Haoomff 怎么搞

by _Haoomff_ @ 2022-05-08 09:38:33

@linyuqikimi 稍微改得多了一些哈，别介意

#include<bits/stdc++.h>
using namespace std;
int main() {
    long long k,m=0,n=0;
    cin>>k;
    for(int i=1;i<=k;i++){
        for(int j=1;j<=i;j++){
            n++;
            m+=i;
            if(n==k){
                cout<<m;
                return 0;
            }
        }
    }
    return 0;
}
