WebApr 5, 2024 · Given a Linked List, create a Complete Binary Tree. The idea is to first find the middle node of the linked list and make it the root of the tree. We then recursively do the same for the left and right halves. The algorithm has mainly two steps. 1) Get the middle of the linked list and make it the root of the tree. WebPython sorts tuples from left to right, so if you arrange your tuples so the first sort key is the first item and so forth, it'll be reasonably efficient. The mapping from a list of tuples to a tree is not clear from what you're describing. Please draw it out, or explain it more thoroughly. For example, your example appears to be:
