How do I rotate an array to the left?
The array can be left rotated by shifting its elements to a position prior to them which can be accomplished by looping through the array and perform the operation arr[j] = arr[j+1]. The first element of the array will be added to the last of rotated array.
How do you rotate an array to the left in Java?

How to write a function that rotates an array?
Write a function rotate (ar [], d, n) that rotates arr [] of size n by d elements. Recommended: Please solve it on “ PRACTICE ” first, before moving on to the solution.
How to rotate an array according to GCD?
If GCD is 1 as is for the above example array (n = 7 and d =2), then elements will be moved within one set only, we just start with temp = arr [0] and keep moving arr [I+d] to arr [I] and finally store temp at the right place. Here is an example for n =12 and d = 3. GCD is 3 and Below is the implementation of the above approach :
