WebMar 13, 2024 · Method 1 (Check one by one) We know that Floyd’s Cycle detection algorithm terminates when fast and slow pointers meet at a common point. We also know that this common point is one of the loop nodes (2 or 3 or 4 or 5 in the above diagram). Store the address of this in a pointer variable say ptr2. WebFast and slow pointers are an extension of the arrays 2 pointers method to linked list. The idea is to iterate through the list with 2 pointers moving at different speeds.
