Given the root of a binary tree, return its maximum depth. A binary tree's maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node.

// height(’12’) = max(height(‘8′), height(’18’)) + 1 = 1 + 1 = 2 The idea is, if we take a closer look at the depth first traversal, we can notice that ...
