How to realize sliding window by Java

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)
