Find closest leaf in binary tree

WebConsider all the leaves of a binary tree, from left to right order, the values of those leaves form a leaf value sequence.. For example, in the given tree above, the leaf value sequence is (6, 7, 4, 9, 8).. Two binary trees are considered leaf-similar if their leaf value sequence is the same.. Return true if and only if the two given trees with head nodes root1 and root2 … WebSep 28, 2009 · The binary tree is traversed from the root node, until both nodes are found. Every time a node is visited, it is added to a dictionary (called parent). Once both nodes are found in the binary tree, the ancestors of node1 are obtained using the dictionary and added to a set (called ancestors). This step is followed in the same manner for node2.
