[LeetCode] 1608. Special Array With X Elements Greater Than or Equal X
You are given an array nums of non-negative integers. nums is considered special if there exists a number x such that there are exactly x numbers in nums that are greater than or equal to x. Notice that x does not have to be an element in nSubarray With Elements Greater Than Varying Threshold
Subarray With Elements Greater Than Varying Threshold You are given an integer array $nums$ and an integer $threshold$. Find any subarray of $nums$ of length $k$ such that every element in the subarray is greater than $threshold / k$. Return the size of a接水问题(NOIP 2010 PJT2)
题目: 使用优先队列。开优先队列:priority_queue<int,vector<int>,greater<int>> que;1.输入输入 n(<=10000),m(<=100)(m<=n)将输入的打水时间存入a数组中。2.处理数据2.1遍历a[i]数组,i<=m时,将a[i]推入que中。 i>m时,将a[i]加上que.front(),再que.pop(),最后将a[i]入队。3.输堆(模板)(优先队列实现)
P3378 堆好麻烦直接偷懒用优先队列吧 优先小队列(堆顶为最小元)创建priority_queue<int, vector<int>, greater<int>> q; #include <bits/stdc++.h> using namespace std; priority_queue<int, vector<int>, greater<int>> q; int n; int main() { scanf1019. Next Greater Node In Linked List
This problem is as same as https://www.cnblogs.com/feiflytech/p/16169025.html class Solution { public int[] nextLargerNodes(ListNode head) { List<Integer> list = new ArrayList<>(); ListNode point = head; while(poin556. Next Greater Element III
This is a similiar problem with https://www.cnblogs.com/feiflytech/p/15862432.html The only differences are: 1. If no larger number can be returned, this problem return -1 2. Need to judge whether the result number is largen then Integer.MAX_VALUE. class496. Next Greater Element I
My solution, time complexity O(m*n): class Solution { public int[] nextGreaterElement(int[] nums1, int[] nums2) { Map<Integer, Integer> map = new HashMap<>(); for(int i=0;i<nums2.length;i++){ map.put(nums2[i3.26

LeetCode 496. Next Greater Element I (下一个更大元素 I) 题目 链接 https://leetcode-cn.com/problems/next-greater-element-i/ 问题描述 nums1 中数字 x 的 下一个更大元素 是指 x 在 nums2 中对应位置 右侧 的 第一个 比 x 大的元素。 给你两个 没有重复元素 的数组sort函数——如何降序排序
sort函数默认是进行升序排序,有两种方式可以进行降序。 使用greater<int>() sort(arr, arr + 5, greater<int>()); 自定义一个比较大小的函数,将大的排前面 bool cmp(int x,int y){ return x > y; } sort(arr,arr + 5,cmp); reference:https://blog.csdn.net/lytwy123/article/d556. Next Greater Element III
This is the similar problem with "31. Next Permutation", the differences are: 1. 31 don't care about whether the "next" is larger or not, but 556 care, 556 need the next is larger than it. 2. 31's input is an array, while 556[亚麻高频题] Leetcode 503. Next Greater Element II(下一个大的元素)
题目描述 & 链接 Leetcode 503. 下一个更大元素 题目思路 1. 单调栈 单调栈经典应用 - 寻找下一个更大元素的位置,这道题不同的是数组是一个循环数组,也就是下一个更大元素位置也可以在当前元素前面。所以不仅要查看后面的元素,也要查看前面元素,对于循环数组的处理一般是将数组拼CF1526C2 Potions (Hard Version)

Given a circular integer array nums (i.e., the next element of nums[nums.length - 1] is nums[0]), return the next greater number for every element in nums. The next greater number of a number x is the first greater number to its traversing-order简单快速排序 (python)
