Detecting the starting point of the cycle (in a linked-list) - As per the behavior of Floyd's algorithm, i.e., from the meeting point ( µ) of the hare H and tortoise T, T starts moving 1 step at a time from µ and H starts moving 1 step at a time from the starting point b of the linked-list and they meet up at the starting point c of the ... WebFeb 27, 2011 · I had a look at question already which talk about algorithm to find loop in a linked list. I have read Floyd's cycle-finding algorithm solution, mentioned at lot of places that we have to take two pointers. One pointer( slower/tortoise ) is increased by one and other pointer( faster/hare ) is increased by 2. When they are equal we find the loop and if … WebMay 6, 2013 · So, there's a cycle, and the hare enters it, running around like crazy. Eventually, the tortoise reaches the first node of the cycle. From this point on, both necessarily stay in the cycle: the only way they can go from a node is to the next node, which eventually leads back to the first node of the cycle. did jenny die of aids in forrest gump
