Challenge: Array rotation

Right rotation

Write Java code to rotate the specified array arr to the right a given number of times.

Return the right-rotated array. k is the nonnegative number of right rotations needed.

For example, let the input k be 2 and the original array before rotation be as follows:

[1, 2, 3, 4, 5, 6]

The resulting right-rotated array arr should look like this:

[5, 6, 1, 2, 3, 4]
