WebMay 27, 2024 · I came across Floyd's Cycle Detection Algorithm, also known as Floyd's Tortoise and Hare Algorithm. The idea behind the algorithm is that, if you have two pointers in a linked list, one moving twice as fast (the hare) than the other (the tortoise), then if they intersect, there is a cycle in the linked list. If they don't intersect, then there ... WebFeb 11, 2024 · A graph cycle is when there is a "loop" or circular reference. This can be a series of edges that connect back to an origin vertex. If a graph has a cycle it is a cyclic graph. To determine if a graph has a cycle, we can traverse the graph and look for a back edge. A back edge is one that connects a vertex to an already visited ancestor. Example:

WebJul 10, 2016 · Remove the Loop. To remove the loop, we need to figure out the last node of the list and point that node to NULL. In the above algorithm, slow and fast pointers meet somewhere in the loop which might not be the start or end node of the loop. Point the near pointer to the first node. And point the far pointer as far as the size of the loop.
