Flattening of linked list leetcode
WebGiven a list that can grow in both horizontal and vertical directions (right and down), flatten it into a singly linked list.The conversion should be in such a way that the down node should be processed before the next node for any node.. A multilevel list is similar to the standard linked list except it has an extra field, down, which points to a vertical list. Web@ankankr Pardon me if I got it wrong. Based on your examples, the problem looks equivalent to pre-order traversal of the list to me. Correct me if I am mistaken.

To detect whether a linked list is a circular linked list, we can use two pointers with different speeds: a pointer and a pointer. We use these two pointers to traverse the linked list. The pointer moves one step at a time, and the pointer moves two steps.

Your task is to flatten the given BST to a sorted list. More formally, you have to make a right-skewed BST from the given BST, i.e., the left child of all the nodes must be NULL, and the value at the right child must be greater than the current node. no wing mirrorsWeb2. Make faster pointer traverse faster. 3. Since the faster pointer is faster than the slow pointer, if it reaches null or points to null , then immediately it is known that the linked list is not circular. 4. If the fast pointer meets slow pointer or points to it , then it is known that the linked list is circular.} nicole fontaine winnipeg
