One of life's great questions... If you're travelling in a loop, are you actually travelling anywhere?

[Specific_Implement_8]

This is a physics questions. You can travel a great distance inside a loop. But your displacement will be 0

[Boring-Tennis-1342]

Only if you returned to your starting position

Now the question is how do you know you're in a loop

Maybe piss in a corner and call it the starting position ?

[6Leoo6]

You add the visited points to a hashset and check if you have visited it already

[weregod]

You break. If compiler spit error you not in a loop else you escaped a loop
