Java for LeetCode 189 Rotate Array

標籤：

Rotate an array of n elements to the right by k steps.

For example, with n = 7 and k = 3, the array [1,2,3,4,5,6,7] is rotated to [5,6,7,1,2,3,4].

解題思路：

JAVA實現如下：

    public void rotate(int[] nums, int k) {        k%=nums.length;        k=nums.length-k;        int[] nums2=new int[k];        for(int i=0;i<k;i++)        nums2[i]=nums[i];        for(int i=0;i<nums.length-k;i++)        nums[i]=nums[i+k];        for(int i=0;i<k;i++)        nums[nums.length-k+i]=nums2[i];    }
