FUNCTION printCorner (root): prints corner nodes (leftmost, rightmost) of the tree
Prerequisite: Queue q, input binary tree root
Example with explanation:
N.B: The nodes are represented by their respective values.
For the above example:
Nodes are represented with their respective values for better understanding.
C++ implementation:
