Below are steps to find the first node of the loop. 1. If a loop is found, initialize a slow pointer to head, let fast pointer be at its position. 2. Move both slow and fast pointers one node at a time. 3. The point at which they meet is the start of the loop. C++. hotel seri malaysia bagan lalang review

Nettet23. jul. 2024 · Given a singly Linked List, detect if it contains a loop or not. Input: Output: True. Input: 1→ 2→ 3→ NULL. Output: False. Generally, the last node of the Linked List points to a NULL pointer, which indicates the end of the Linked List. But in Linked List containing a loop, the last node of the Linked List points to some internal node ... Nettet12. jul. 2024 · Below are the steps to detect a loop in a Linked List, Take two pointers ptr1 and ptr2 and initialize them to the start node. Traverse the Linked List using both the pointers but move ptr1 one node at a time and ptr2 two nodes at a time. As ptr2 is moving with double the speed, it will be ahead of ptr1. So check if ptr2 encounters NULL. Nettet3. mar. 2024 · A Computer Science portal for geeks.
