North Carolina 511 periodically reorders route updates so the most recent entries appear first. Implement a function that rotates an integer array to the right by k positions in place and returns the same array.
A right rotation moves each element k positions toward the end. Elements that pass the last index wrap around to the beginning. Aim for linear time and constant extra space.
nums, a mutable list of integers, and k, a nonnegative integer.nums modified in place.k is larger than the array length, treat it modulo the array length.def rotate(nums, k):
