WebJul 9, 2009 · A simple algorithm called Floyd's algorithm is to have two pointers, a and b, which both start at the first element in the linked list. Then at each step you increment a once and b twice. Repeat until you either reach the end of the list (no loop), or a == b (the linked list contains a loop). Another algorithm is Brent's algorithm.

WebMar 16, 2016 · 1. This is not an efficient way to implement circular buffer because pop (0) is O (n) operation in the list. pop (0) removes the first element in the list and all elements have to be shifted to the left. Use collections.deque with maxlen attribute instead. deque has O (1) operation for append and pop. – Vlad Bezden.
