A binary array is an array consisting of only 0s and 1s.

You are given a binary array "arr" of size ‘N’. Your task is to sort the given array and return this array after sorting.

You have been given a matrix of ‘N’ rows and ‘M’ columns filled up with integers. Find the minimum sum that can be obtained from a path which from cell (x,y) and ends at the top left corner (1,1).

From any cell in a row, we can move to the right, down or the down right diagonal cell. So from a particular cell (row, col), we can move to the following three cells:

Down: (row+1,col)
Right: (row, col+1)
Down right diagonal: (row+1, col+1)

You are given a reference/address of a node in a connected undirected graph containing N nodes and M edges. You are supposed to return a clone of the given graph which is nothing but a deep copy. Each node in the graph contains an integer “data” and an array/list of its neighbours.

The structure of the graphNode class is as follows:

class graphNode 
{  
    public:
        int data;
        vector<graphNode*> neighbours;
}

Note :

1. Nodes are numbered from 1 to N.

2. Your solution will run on multiple test cases. If you are using global variables make sure to clear them.

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.
