WebIDEA –. In order to flatten a binary tree, we will first find the rightmost element of the left subtree and after we got the rightmost element we will link the right-pointer of that node with a right subtree of a given tree. In step 2 we will link the right pointer of the root node with the left-subtree and set the left-subtree as null. WebSep 21, 2024 · Fundamentally, it seems like we're just flattening the tree onto a string and using string comparison functions to find the similarity between the trees. So, I would imagine as long as the ordering is consistent between both trees, either of the three ordering schemes should work fine.
