you were not checking condition of empty stack accepted solution: https://www.codechef.com/viewsolution/29828582
thanks mr linesekarenge
is it possible that the stack will empty ? because the the first element will always in the stack.
If all points are distinct then obviously stack will never be empty. But if they are not then your ccw function will return 0, if any two points of triangle are same. Which may lead to empty stack
