@Stare

#include <bits/stdc++.h>
using namespace std;
int main()
{
    int k;
    cin>>k;
    int b=1;
    int bnum=0;
    int tnum=0;
    while(tnum<k)
    {
        for (int t = 0; t < b and tnum < k; ++t, ++tnum)  {
            bnum+=b;
        }
        b++;
    }
    cout <<bnum;
    return 0;
}

这样改就行了
