WebApr 10, 2024 · Create a stack and push the root node onto it twice. While the stack is not empty, repeat the following steps: a. Pop two nodes from the stack, say node1 and node2. b. If both node1 and node2 are null, continue to the next iteration. c. If one of the nodes is null and the other is not, return false as it is not a mirror. d. WebJan 17, 2024 · Given a binary tree, delete a node from it by making sure that the tree shrinks from the bottom (i.e. the deleted node is replaced by the bottom-most and rightmost node). This is different from BST deletion. Here we do not have any order among elements, so we replace them with the last element.
