You are given an array A of size N.

You are also given an integer X and a direction DIR. You need to rotate the array A by X positions in the direction specified by DIR.

DIR can be:

• 'LEFT': Rotate the array to the left by X positions.
• 'RIGHT': Rotate the array to the right by X positions.

Return the resulting rotated array.

For example:

Input :
A = [6, 2, 6, 1], X = 1, DIR = ‘LEFT’

Output :
2 6 1 6

Explanation: Rotate array ‘A’ to the left one time.
[6, 2, 6, 1] => [2, 6, 1, 6]

Given a string, determine if it is a palindrome, considering only alphanumeric characters.

Palindrome

A palindrome is a word, number, phrase, or other sequences of characters which read the same backwards and forwards.

Example:

If the input string happens to be, "malayalam" then as we see that this word can be read the same as forward and backwards, it is said to be a valid palindrome.

The expected output for this example will print, 'true'.

From that being said, you are required to return a boolean value from the function that has been asked to implement.
