We had given a number and a series where we need to print that series followed by the no of lines given i.e n value. We need to cover all test cases in it.

Ninja has been given two sorted integer arrays/lists ‘ARR1’ and ‘ARR2’ of size ‘M’ and ‘N’. Ninja has to merge these sorted arrays/lists into ‘ARR1’ as one sorted array. You may have to assume that ‘ARR1’ has a size equal to ‘M’ + ‘N’ such that ‘ARR1’ has enough space to add all the elements of ‘ARR2’ in ‘ARR1’.

For example:

‘ARR1’ = [3 6 9 0 0]
‘ARR2’ = [4 10]
After merging the ‘ARR1’ and ‘ARR2’ in ‘ARR1’. 
‘ARR1’ = [3 4 6 9 10]

You have been given a root node of the binary search tree and a positive integer value. You need to perform an insertion operation i.e. inserting a new node with the given value in the given binary search tree such that the resultant tree is also a binary search tree.

If there can be more than one possible tree, then you can return any.

Note :

A binary search tree is a binary tree data structure, with the following properties :

    a. The left subtree of any node contains nodes with a value less than the node’s value.

    b. The right subtree of any node contains nodes with a value equal to or greater than the node’s value.

    c. Right, and left subtrees are also binary search trees.
It is guaranteed that,

    d. All nodes in the given tree are distinct positive integers.

    e. The given BST does not contain any node with a given integer value.

Example, below the tree, is a binary search tree.

Below the tree is not a BST as node ‘2’ is less than node ‘3’ but ‘2’ is the right child of ‘3’, and node ‘6’ is greater than node ‘5’ but it is in the left subtree of node ‘5’.
