Invert a Binary Value. Kowalski should inverse binary tree. Now you can pass that coding interview no problem.
This example bitwise-inverts all binary values given in the input line by line. In the flip operation the leftmost node becomes the root of the flipped tree and its parent becomes its right child and the right sibling becomes its left child and the same. Given the root of a binary tree invert the tree and return its root.
