It works on my computer, but judgement result is Wrong Answer.

#include <stdio.h>
#include <math.h>

#define MAXSIZE 65536

int main()
{
  unsigned long int value = 0;
  int counter = -1;
  int i = 0;
  unsigned long int a[MAXSIZE];
  while (scanf("%lu", &value) != EOF)
  {
    a[++counter] = value;
  }
  for (i = counter; i > -1; i--)
  {
    printf("%.4f\n", sqrt((double)a[i]));
  }
  return 0;
}

be confirmed that input limit is covered by your program

Try to use unsigned long long, because 10^18>2^32

the array is too small,you can try global array to solve it ,but it should be large,at least

500000
