To see why I got WA, I try this code:

if (k>1)
{
  k=0; cout<<1/k<<endl;
}
else
{
  cout<<0<<endl;
  return;
}

This program got WA !!!!!!!
Can you explain it to me??????

Obviously Test#1 is k=1, and I got WA @ 2
Not CRASH, but WA!!!

Admin, can I say that something had gone wrong??????

Hope to be replied soon.

Validator program has been fixed. Problem has been rejudged. 6 Authors lost AC.

You now have WA#1. Thank you!
