Given an array/list 'ARR' of integers and a position ‘M’. You have to reverse the array after that position.

Example:

We have an array ARR = {1, 2, 3, 4, 5, 6} and M = 3 , considering 0 
based indexing so the subarray {5, 6} will be reversed and our 
output array will be {1, 2, 3, 4, 6, 5}.

Given an array 'arr' with 'n' elements, the task is to rotate the array to the left by 'k' steps, where 'k' is non-negative.

Example:

'arr '= [1,2,3,4,5]
'k' = 1  rotated array = [2,3,4,5,1]
'k' = 2  rotated array = [3,4,5,1,2]
'k' = 3  rotated array = [4,5,1,2,3] and so on.

I was given an array and was asked to find the output If I sort the given array.

Bubble Sort is one of the sorting algorithms that works by repeatedly swapping the adjacent elements of the array if they are not in sorted order.

You are given an unsorted array consisting of N non-negative integers. Your task is to sort the array in non-decreasing order using the Bubble Sort algorithm.

For Example:

Bubble Sort implementation for the given array:  {6,2,8,4,10} is shown below :-

You are given a Doubly linked list, where every node in the linked list contains two pointers ‘next’ and ‘prev’ which point to the next node and previous node in the list respectively. All nodes have some positive integer value associated with them. Your task is to insert an integer value ‘VAL’ in the linked list at a given position ‘K’.

Note:

The position given will always be less than or equal to the length of the linked list.
Assume that the Indexing for the linked list starts from 0.

EXAMPLE:

Input :
‘K’ = 3, ‘VAL’ = 4
list = [1, 2, 3]
Output: [1, 2, 3, 4]

The ‘VAL’ = 4, is inserted at end of the above doubly linked list.
