Binary Tree Left and Right View Problem Statement Given the root of a Binary Tree, return its right and left views. The Right View of a Binary Tree is a list of nodes that can be seen when the tree is viewed from the right side, starting from the top. The Left View of a Binary Tree is a list of nodes that can be seen when the tree is viewed from the left side, starting from the top. Input Specification The input will be a sequence of integers representing the binary tree in a level order fashion. A value of 1 indicates a null child. Output Specification Return two lists of integers. The first list should represent the Left View traversal, and the second list should represent the Right View traversal.
