A left rotation operation on an array shifts each of the array's elements unit to the left. For example, if left rotations are performed on array , then the array would become . Note that the lowest index item moves to the highest index in a rotation. This is called a circular array.
Given an array of integers and a number, , perform left rotations on the array. Return the updated array to be printed as a single line of space-separated integers.
