Rotatearray.py

# You have been given a random integer array/list(ARR) of size N. Write a function that rotates the given array/list by D elements(towards the left).

# Input format :
# The first line contains an Integer 't' which denotes the number of test cases or queries to be run. Then the test cases follow.
# First line of each test case or query contains an integer 'N' representing the size of the array/list.
# Second line contains 'N' single space separated integers representing the elements in the array/list.
# Third line contains the value of 'D' by which the array/list needs to be rotated.
