WebNow the problem is to find the entrance of the cycle. Algorithm. Floyd's algorithm consists of two phases and uses two pointers, usually called tortoise and hare. In phase 1, hare = nums[nums[hare]] is twice as fast as tortoise = nums[tortoise]. Since the hare goes fast, it would be the first to enter the cycle and run around the cycle.

WebJan 14, 2024 · We can use the Floyd's cycle-finding algorithm (also known as the "tortoise and hare" algorithm) to check for a loop in the array. We initialize two pointers, slow and fast, and move them at different speeds through the array. If there is a loop, the fast pointer will eventually catch up to the slow pointer, and we can return true.
