可怜的419名，给你参考一下：
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<math.h>
#include<time.h>
#include<windows.h>
int k,i,a,ans,x;
int main(){
freopen("coin.in","r",stdin);
freopen("coin.out","w",stdout);
scanf("%d",&k);
do{
i++;
if (x+i<=k) x+=i; else break;
a++;
}while(1);
ans=(k-x)*(a+1);
for (i=1;i<=a;i++)
ans+=i*i;
printf("%d\n",ans);
return 0;
}

忘记不要加文件了
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<math.h>
#include<time.h>
#include<windows.h>
int k,i,a,ans,x;
int main(){
scanf("%d",&k);
do{
i++;
if (x+i<=k) x+=i; else break;
a++;
}while(1);
ans=(k-x)*(a+1);
for (i=1;i<=a;i++)
ans+=i*i;
printf("%d\n",ans);
return 0;

#include<iostream>
#include<math.h>
using namespace std;
int n,s,s2,s3;
int main()
{
cin>>n;
while(s2<n)
{
s++;
s2+=s;
}
for (int i=1;i<=s;i++)
s3+=pow(i,2);
s3-=s*(s2-n);
cout<<s3;
