try this:
double a [128*1024]

Re: Why is WA for Test 9? Pls. Help me. Aleksa_Markoni 23 Nov 2008 01:32

use dinamic memory try
double *a = (double *) malloc (sizeof(double)*128*1024);
and when you done before return
free (a);
thats all :)

Could you tell me why it should use dinamic memory ?
Thank you!

There is no need to use dinamic memory ...
Just make sure that your array is large enough.
But I wonder why the result I get is TLE ...
this is my code:
#include<stdio.h>
#include<string.h>
#include<math.h>

double a[100010];//make it larger and then I got AC

int main()
{
    int k=0;
    while(scanf("%lf",&a[k])!=EOF)k++;
    while(k)
        printf("%.4lf\n",sqrt(a[--k]));

    return 0;
}
