In this article Xiaobian for you to introduce in detail "Java how to achieve sliding window", the content is detailed, the steps are clear, the details are handled properly, I hope this "Java how to achieve sliding window" article can help you solve doubts, following the editor's ideas slowly in-depth, together to learn new knowledge.

Ideas for solving the problem:

Use queues to implement sliding windows

Public int [] rotate (int [] nums,int k) {LinkedList queue = new LinkedList (); for (int num:nums) {queue.offer (num);} for (int iTunes I {return value;}). ToArray ();}

Optimization algorithm: exchange space for time: copy an array of the same dimension and replace the position of the original array.

Class Solution {public void rotate (int [] nums,int k) {int [] nums1= Arrays.copyOfRange (nums,0,nums.length); for (int I = 0 I)
