Preorder tree traversal, inorder tree traversal, and postorder tree traversal computer science concept explained in under 5 minutes. This is the easiest way IMO to remember all 3 of them. At the root of the tree, start traversing for all 3 methods counterclockwise. From there, preorder requires you the first time seeing the node to print it, inorder is the second time, post is the last time. Make sure to draw out the nulls when doing this yourself so you do the traversals correctly. #leetcode #t
