[HDU] 1213 - How Many Tables [基础并查集,求父节点个数] 1856 -More is better [基础并查集,注意内存,HDU数据水了,不用离散化,注意路径压缩的方式就好]代码链接:http://blog.csdn.net/catherinetang0919/article/details/24815507 1232--畅通工程---[基础并查集,没什么好说的,最基础的题,代码就免了,小小纪念一下,十分钟内写好代码然后1A] 1102-Constructing…

今天开始第一天记录刷题,本人编程小白,如果有写的不对.或者能更完善的地方请个位批评指正! 准备按tag刷,第一个tag是array: 这个是array的第一道题:11. Container With Most Water Given n non-negative integers a1, a2, ..., an , where each represents a point at coordinate (i, ai). n vertical lines are drawn such that t…

Given n non-negative integers representing an elevation map where the width of each bar is 1, compute how much water it is able to trap after raining. The above elevation map is represented by array [0,1,0,2,1,0,1,3,2,1,2,1]. In this case, 6 units of…

python 三元表达式 之前学习的Python提到了对于类似C语言的三元条件表达式condition ? true_part : false_part,虽然Python没有三目运算符(?:),但也有类似的替代方案,那就是true_part if condition else false_part. 代码如下: >>> >>> >>> "Fire" if True else "Water" 'Fire' >…

monotone_matrix_search() and sorted_matrix_search() are techniques that deal with the problem of efficiently finding largest entries in matrices with certain structural properties. Many concrete problems can be modelled as matrix search problems, and…

Given a sorted array and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order. You may assume no duplicates in the array. Example 1: Input: [1,3,5,6], 5 Output: 2 Example 2:…

原题目:Search for a Range, 现在题目改为: 34. Find First and Last Position of Element in Sorted Array Given an array of integers nums sorted in ascending order, find the starting and ending position of a given target value. Your algorithm's runtime complexity…

What is a search problem: A solution to a search problem is a sequence of actions (a path) from s0 to a goal state. It is optimal if it has minimum sum of step costs. Traditional Problem: Tower of Hanoi. 解释:搜索问题可以解释为从original state to target state构建的…
