Fast and slow pointer technique in Linked List
WebFeb 3, 2024 · Use slow and fast pointer to slove this problem Approach used two pointer to find the middle node where the slow pointer will move k steps and the fast pointer will move 2k steps. At the end of the iteration the slow pointer will end on the middle node and fast will land on the end of the list. Complexity Time complexity: O (n) Space complexity: WebOn each step, the fast pointer advance by 2 nodes and the slow pointer by 1 node. This way, the slow pointer reaches the middle node while the fast one reaches the end. This is because the slow pointer moves at half the speed. {4/5} Of course, this approach has some variants. For example, the pointers can start at different locations or have ... WebSep 10, 2012 · if the fast pointer reaches the end of the list, the slow pointer points to the middle of the list, so now: the slow pointer advances to the end of the list, and in each step: it pops one element from the stack and compares it to the current list element (if they are not equal, return false) gaming industry revenue by year
