Fast And Slow Pointer Approach. The fast pointer typically moves faster than the slow pointer. Th

The fast pointer typically moves faster than the slow pointer. The two pointers move through the data structure at different speeds, and this relative movement helps in findin Jan 26, 2024 · This technique is commonly known as the ‘Fast & Slow Pointer’ or ‘Tortoise and Hare Algorithm,’ and it essentially embodies Floyd’s Cycle… Feb 12, 2024 · Hey coders !! In problem-solving, we often use a technique called Fast and Slow Pointers. The Fast and Slow Pointers pattern For the problem of detecting cycles in a linked list, there is a universal solution—the fast and slow pointer method (Floyd’s Cycle Detection Algorithm). when the fast pointer reaches the end , the slow pointer points to middle node . After watching this video, you'll understand slow and fast pointers thoroughly. 🔹 fast = head while fast and fast. Example 3: Finding the Middle of a Linked List This is another very common use case. Its concern is often to identify a pattern or structure in Aug 28, 2025 · The fast and slow pointer technique, also known as the Floyd’s Tortoise and Hare algorithm, is a popular algorithmic technique used in computer science and data structures to solve various Oct 20, 2018 · The fast pointer actually become useless after finding the middle point After we find the middle node (after fast reach to the end), we split the linked list to left sublist (that’s why I used a prevSlow pointer, since we need to cut the list off at the middle pointer in order to use the left sublist!) and right sublist, which would also be If the fast pointer moves 3 steps and slow pointer at 1 step, it is not guaranteed for both pointers to meet in cycles containing even number of nodes. If a cycle exists, the two pointers will eventually meet during traversal. References:1.
