Solution For the bottom-up solution to work, we need to know the length of the Linked List. At the worst case if this is not known in advance, iterating a Linked List will cost us O(n). The basic idea of this bottom-up solution is basically to use the inorder traversal pattern. It first processes the left subtree, the current node, then the right subtree. When it processes the left subtree, the inorder recursion will traverse the list from left to right in the same exact order that makes it possible to do this in O(n) complexity since every node will get visited exactly once and the process complete when it visits all the nodes.
On the other hands, inserting each number in the same order 1, 2, 3, …, 7 to a BST will create imbalance BST with 1 at its root and the remaining numbers will be expanded on its right most path. With such an imbalance BST, the lookup will have worst-case complexity O(n). It defeats the purpose of using BST in the first place. To create a balanced BST from a sorted list, the common approach is to use a divide-and-conquer pattern in a top-down fashion; inserting the middle node and split the list into two parts pivoting on this middle node, and then recurse left and right.
For example for a sequence of [5, 1, 1, 5], the answer is [5,5]. [5,1] or [5,1,5] or [1,1,5] are not valid candidates because it contains adjacent items of the original sequence. Variation 3: Max Product of Subarray. Variation 4: Max Sum of Sub [2D] Matrix. Test Cases 1.  – single item 2. [4,-5,1,5,-6,9] – general case; max = 9 3. [0,0,-1,0,-4] – zeroes and negatives; max = 0 4. [-7, -2, -3, -11, -4, -5] – all negatives; max = -2 Solution There exists solution with O(1) space and O(n) runtime complexity for this problem.
