I'm getting WA even though all of the input I was checking gave the same output as accepted codes. Can someone explain what's wrong or give me some nasty inputs that give wrong outputs? Quick reply would be really appreciated.

#include <stdio.h>
#include <stdbool.h>

struct point
{
int x,y ...

If I just compare every two points to see whether one covers another, will I get TLE?

Also, does output need to be sorted in some way or may be just printed in a random order?

But now I don't know why I'm getting WA. Am I using a wrong algorithm? Thanks in advance.

Code in C.

#include <stdio.h>

int main()
{
int n,a,m,i;
double x,y,p,odla,odlb,odlc,odld;
scanf("%d %d",&n,&a);
while (n!=0)
{
m=0;
for (i=0;i<n;i++)
{
scanf("%lf %lf",&x,&y);
odla=x*x+y*y;
odlb ...

Wow, how did I forget about that, thanks.

Altought only one test case gave incorrect output, it made me realise quite a few errors in code, so thanks for that. Got AC now.

Why am I getting runtime error? Code in C. Thanks for help.

Why do I get wrong answer? Seems to work on every sample input:
