card-tricks: Check if index is >= len(slice)

[CodeBleu]

Adjusting so the test will now fail if the index value is greater than or equal to the size of the slice.

Hey @CodeBleu.

Sorry for the delay in reviewing this. Still interested in working on this?

In this case, I'd suggest to add a new test where the index is strictly bigger than len(slice). That way we have a test for when the index is equal to len(slice) and another one for when it is bigger.

@andrerfcsantos Does there really need to be 2 tests? Not sure what the benefit is, if an = or > value is used. There would not be any use case to just check for =, right? Both will fail. Maybe I'm missing something, but I don't see it any different than writing a test that checks for a specific number greater than either...hence just test for >
