You have been given a Binary Tree of integers.

Your task is to print the Right view of it.

The right view of a Binary Tree is a set of nodes visible when the tree is viewed from the Right side and the nodes are printed from top to bottom order.

Given a binary tree and the value of two nodes, find the distance between the given two nodes of the Binary Tree.

Distance between two nodes is defined as the minimum number of edges in the path from one node to another.

You are given a 2D matrix ‘MATRIX’ of ‘N’*’M’ dimension. You must check whether a given number ‘target’ is present in the matrix.

The following properties apply to the given matrix:

1. In each row, integers are sorted from left to right.
2. Each row's first integer is greater than the previous row's last integer.

Example:

Input:
'MATRIX' = [ [1, 3, 5, 7], [10, 11, 16, 20], [23, 30, 34, 60] ], 'TARGET' = 3 
Output:1
Explanation: Since the given number ‘TARGET’ is present in the matrix, we return true.
