LeetCode 189---Rotate Array

题目链接：LeetCode 189—Rotate Array

题目大意：将给定顺序数组（1–n）循环右移k位，如：

n=7,k=3
则将[1,2,3,4,5,6,7] –> [5,6,7,1,2,3,4]

---

实现代码如下：

public class Problem189 {    public static void main(String[] args) {        // TODO Auto-generated method stub    }     public void rotate(int[] nums, int k) {         int start = 0;         while (start < nums.length - 1) {                k %= nums.length - start;                if (k == 0) break;                for (int i = nums.length - k; i < nums.length; i++) {                    int tmp = nums[start];                    nums[start++] = nums[i];                    nums[i] = tmp;                }            }     }}
