数的分解

[我真的是c了]

#include <stdio.h>
#include <stdlib.h>
int judge(int n)
{
  while(n)
  {
    if(n % 10 == 2 || n % 10 == 4)
    {
      return 0;
    }
    n /= 10;
  }
  return 1;
}
int main(int argc, char *argv[])
{
  int i, j, k;
  int ans = 0;
  for(i = 1; i <= 2019; i ++)
  {
    for(j = 1; j <= 2019; j ++)
    {
      k = 2019 - i - j;
      if(judge(i) && judge(j) && judge(k))
      {
        if(i < j && j < k)
        {
          ans ++;
        }
      }
    }
  }
  printf("%d\n", ans);
  return 0;
}
