代码还原：


include <cstdio>
using namespace std;
int main( ) {
   int k;
   scanf("%d",&k); 
   long long sum = 0;
   int cur = 1; 
   int rst = 1; 
   for(int i = 1; i <= 0; i++) { 
      sum += cur;
      rst--;
      if(rst == 0) {
      cur++;
      rst = cur; 
        } 
      }
      printf("%lld\n",sum); 
      return 0; 
 }

#include <iostream>
#include <cstdio>
using namespace std;
int main( )
{
    int k;
    scanf("%d",&k); 
    long long sum = 0;
    int cur = 1; 
    int rst = 1; 
    for(int i = 1; i <= k; i++)
    { 
      sum += cur;
      rst--;
      if(rst == 0) {cur++;rst = cur; } 
    }
    printf("%lld\n",sum); 
    return 0;
}

你把

for(int i = 1; i <= k; i++)

写成了

for(int i = 1; i <= 0; i++)
