Arrays
A left rotation operation on an array shifts each of the array's elements 1 unit to the left. For example, if 2 left rotations are performed on array [1,2,3,4,5] , then the array would become [3,4,5,1,2] . Given an array a of n integers and a number, d , perform d left rotations on the array. Return the updated array to be printed as a single line of space-separated integers.
