Lintcode 1334. Rotate Array (Easy) (Python)

1334. Rotate Array

Description:

Given an array, rotate the array to the right by k steps, where k is non-negative.

Example

Example 1:

Input: [1,2,3,4,5,6,7] and k = 3
Output: [5,6,7,1,2,3,4]
Explanation:
rotate 1 steps to the right: [7,1,2,3,4,5,6]
rotate 2 steps to the right: [6,7,1,2,3,4,5]
rotate 3 steps to the right: [5,6,7,1,2,3,4]
Example 2:

Input: [-1,-100,3,99] and k = 2
Output: [3,99,-1,-100]
Explanation:
rotate 1 steps to the right: [99,-1,-100,3]
rotate 2 steps to the right: [3,99,-1,-100]

Code:

class Solution:
    """
    @param nums: an array
    @param k: an integer
    @return: rotate the array to the right by k steps
    """
    def rotate(self, nums, k):
        # Write your code here
        tmp = nums[(len(nums)-k):]
        return tmp + nums[:(len(nums)-k)]
