- Q2. Detect a loop in linked list
- Ans.
Loop in linked list can be detected using Floyd's cycle-finding algorithm.
Floyd's cycle-finding algorithm uses two pointers, one moving at twice the speed of the other.
If there is a loop, the faster pointer will eventually catch up to the slower pointer.
If there is no loop, the faster pointer will reach the end of the list.
Time complexity of this algorithm is O(n) and space complexity is O(1).
