Kth Minimum Clique 题目描述 Given a vertex-weighted graph with N vertices, find out the K-th minimum weighted clique. A subset of vertices of an undirected graph is called clique if and only if every two distinct vertices in the subset are adjacent. The…

Kth Minimum Clique 题意 给出n(n<100)个点的邻接表,和n个点的权值,求第k大的团(完全子图) 分析 n很小,并且好像没有什么算法和这个有关系,所以可以往暴力枚举的方向想,那么问题就变成了如果枚举?很容易发现一个问题,如何才能补充不漏地枚举呢?肯定要遵循一定的顺序,集合类问题一般是从已选的最后一个点的顺序往后枚举,这样就可以不重不漏了,那怎么实现第k大的,使用优先队列即可.邻接表使用bitmap存储方便操作,可以说是一道Bitmap入门题? #include<bits/…

[POJ2104][HDU2665]K-th Number Description You are working for Macrohard company in data structures department. After failing your previous task about key insertion you were asked to write a new data structure that would be able to return quickly k-th…

题目如下: Given a set of points in the xy-plane, determine the minimum area of any rectangle formed from these points, with sides not necessarily parallel to the x and y axes. If there isn't any rectangle, return 0. Example 1: Input: [[1,2],[2,1],[1,0],[…

[LeetCode]452. Minimum Number of Arrows to Burst Balloons 解题报告(Python) 标签(空格分隔): LeetCode 题目地址:https://leetcode.com/problems/minimum-number-of-arrows-to-burst-balloons/description/ 题目描述: There are a number of spherical balloons spread in two-dimensio…

[题解]魔改版线性基 魔改版线性基解决此类问题. 联系线性空间的性质,我们直接可以构造出这样的基: \[ 100000 \\ 010000 \\ 000010 \\ 000001 \] 使得每个基的最高位是唯一的,我们的目的是要能够保证从上往下一直异或一直变大,所以不能使基出现这样的情况: \[ 100001 \\ 000001 \] 一个不能从上往下一直异或一直变大的例子. 考虑如何构造\(kth\) 大(小),考虑这样的性质,我们记\(a_i\)表示从下往上第\(i\)个基,显然从\(0\)…

今天看到LeetCode OJ题目下方多了"Show Tags"功能.我觉着挺好,方便刚開始学习的人分类练习.同一时候也是解题时的思路提示. [题目] Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2). Find the minimum element. You may assume no…

题目如下: 解题思路:本题和[leetcode]583. Delete Operation for Two Strings 类似,区别在于word1[i] != word2[j]的时候,是删除word1[i]还是word2[j]取决于min(dp[i-1][j]+ord(word1[i-1]),dp[i][j-1]+ord(word2[j-1])). 代码如下: class Solution(object): def minimumDeleteSum(self, s1, s2): ""…
