Solution in C (GCC 9.2.1) (judge verdict: Wrong Answer)

#include <stdio.h>

int main(void){
  int n;
  scanf("%d",&n);

  int tmp=n;
  int c,d=0,ans[11];

  if(tmp>=26){
    while(tmp>=26){
      c=tmp%26;
      tmp=tmp/26;
      ans[d]=c;
      d++;
    }
    ans[d]=tmp;
    d++;
  }else{
    ans[0]=tmp;
    d=1;
  }

  for(int i=d-1;i>=0;i--){
    if(ans[i]==0){
      printf("%c",122);
    }else{
      printf("%c",ans[i]+96);
    }
  }

  printf("\n");

  return 0;
}
