/sliding-window-maximum/ 英文版:https://leetcode.com/problems/sliding-window-maximum/给定一个数组nums,有一个大小为k的滑动窗口从数组的最左侧移动到数组的最右侧。你只可以看到在滑动窗口k内的数字。滑动窗口每次只向右移动一位。返回滑动窗口最大值。 示例: 输入:nums= [1,3,-1,-3,5,3,6,7], 和...
Can you solve this real interview question? Sliding Window Maximum - You are given an array of integers nums, there is a sliding window of size k which is moving from the very left of the array to the very right. You can only see the k numbers in the win
分析: 开始觉得题目的形式很眼熟,感觉应该用Max Heap解。但是显然Max Heap的复杂度是O(n*logK),事实上应该用类似与插入排序的手法,利用双向队列求解。遍历数组,每遇到一个数就与队列的末尾进行比较,若队列末尾的数小于当前数,则队列末尾退出队列,如此往复,知道队列为空,或者队列里的数都大于当前数,最后插入当前数...
