这题是典型的堆排序算法,只是比一般的堆算法多了删除的操作,有两件事需要做: 1 用一个hash表存储从输入数组索引到堆数组(用于实现堆的那个数组)所以的映射,以便在需要删除一个元素的时候能迅速定位到堆数组中的位置 2用一个set保存已经被删除的元素索引(这里指的是输入数组索引),这一点可选;还有一种做法就是直接将已删除元素的值设为最小INT_MIN,不过在leetcode里面并没有说清楚数据范围 class Solution { public: unordered_map<int, int>…

原题链接 题意: 给定一个数组数字,有一个大小为k的滑动窗口,它从数组的最左边移动到最右边.你只能在窗口看到k个数字.每次滑动窗口向右移动一个位置. 记录每一次窗口内的最大值,返回记录的值. 思路: 解法一: 一开始用的c++迭代器来模拟窗口,每移动一次就遍历一次找出最大值填入返回数组中. 效率非常低 Runtime: 108 ms, faster than 7.98% of C++ class Solution { public: vector<int> maxSlidingWindow(v…

这道题是lintcode上的一道题,当然leetcode上同样有. 本题需要寻找O(N)复杂度的算法. 解体思路比较有特点,所以容易想到参考 最小栈 的解题办法. 但是最小栈用栈维护最小值很直观,这道题是队列,用什么数据结构好呢?也许看完暴力解会有点启发. 但是思路还是一样的,最大的要在最前面(直接获取结果),小的值在后面保留下来(防止之后遍历到的时候丢失数据).并且某值出窗口的时候需要判断是否要修改排在最前面的值. 一.暴力解 当然直观看,暴力求解是 O(NK)的复杂度,大体的代码如下:(写的…

滑动窗口基础 滑动窗口常用来解决求字符串子串问题,借助map和计数器,其能在O(n)时间复杂度求子串问题.滑动窗口和双指针(Two pointers)有些类似,可以理解为往同一个方向走的双指针.常用滑动窗口代码框架如下: //3. Longest Substring Without Repeating Characters int lengthOfLongestSubstring(string s) { vector<,); //用于对窗口内的各个字符计数 ,end=,res=; //窗口计数器…

Median is the middle value in an ordered integer list. If the size of the list is even, there is no middle value. So the median is the mean of the two middle value. Examples: [2,3,4] , the median is 3 [2,3], the median is (2 + 3) / 2 = 2.5 Given an a…
