题意:
给你n个数和一个k
把n分成连续的n-k+1个区间
第一行按顺序输出每个区间的最小值,第二行是最大值。
思路:
单调队列的模板题,这里注意的是插入队尾的时候需要二分加速
代码:
#include"stdio.h"
#include"algorithm"
#include"string.h"
#include"iostream"
#include"queue"
#include...

单调队列经典题之一。【思路】设置两个单调队列分别记录最大值和最小值。对于每一个新读入的数字,进行两次操作(对于求最大值和最小值中的某一个而言),一是若队首不在滑窗范围内则删去;二是删去队末比当前值小(或大)的值,并将当前值插入对尾。每一次的最小(大)值就是当前单调队列的队首。【错误点】一定要写whi...

1. 问题描述 给定一个整数数组和一个大小为k的滑动窗口,滑动窗口每次从左到右移动一个数字,返回每次滑动窗口中的最大值。
2. 方法与思路 Method 1:最朴素的解法就是将窗口在数组上进行滑动,每滑动一次求一下窗口的最值。时间复杂度O(nk)O(nk)。
Method 2:还有就是使用平衡二叉树。
I. 取出数组前kk个元素,构建平衡二叉树。
II....
