The algorithm needs linear time in the number of nodes. Doing an early return would simplify your code. As you don't allocate any resources, there goes the only argument against. Doing data-flow analysis is much more involved.

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. WebMar 19, 2024 · Floyd’s cycle detection algorithm is a pointer algorithm that uses only two pointers, moving through the sequence at different speeds. The article states the usage …
WebApr 23, 2015 · Using Floyd Cycle Detection algorithm (fast and slow pointer), we will be able to actually get the value of B. Then the rest of task would be very simple, we simply check whether this value will be 1 or not. You may ask: what if value "1" also appears in the cycle and we are skipping over it. Well, in that case, the value that slow and fast are ... WebAug 10, 2015 · In O (n) time and O (1) space, determine whether a linked list contains a cycle.
