Given an m x n matrix of non-negative integers representing the height of each unit cell in a continent, the "Pacific ocean" touches the left and top edges of the matrix and the "Atlantic ocean" touches the right and bottom edges. Wate…

Given an m x n matrix of positive integers representing the height of each unit cell in a 2D elevation map, compute the volume of water it is able to trap after raining. Note: Both m and n are less than 110. The height of each unit cell is greater th…

You are given two jugs with capacities x and y litres. There is an infinite amount of water supply available. You need to determine whether it is possible to measure exactly z litres using these two jugs. If z liters of water is measurable, you must…

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. For example, Given [0,1,0,2,1,0,1,3,2,1,2,1], return 6. The above elevation map is represented by a…

Given n non-negative integers a1, a2, ..., an, where each represents a point at coordinate (i, ai). n vertical lines are drawn such that the two endpoints of line i is at (i, ai) and (i, 0). Find two lines, which together with x-axis forms a containe…

炎炎夏日,还是呆在空调房里切切题吧. Container With Most Water,题意其实有点噱头,简化下就是,给一个数组,恩,就叫 height 吧,从中任选两项 i 和 j(i <= j),使得 Math.min(height[i], height[j]) * (j - i) 最大化,求解这个最大值. O(n^2) O(n^2) 复杂度的解法非常容易想到,直接两两枚举. var maxArea = function(height) { var len = height.length;…

题目描述: Given n non-negative integers a1, a2, ..., an, where each represents a point at coordinate (i, ai). n vertical lines are drawn such that the two endpoints of line i is at (i, ai) and (i, 0). Find two lines, which together with x-axis forms a co…

前两天在论坛里碰到有朋友问关于使用fluent仿真流固耦合,使用hypermesh作为前处理时的耦合面的方法,刚好今天有点时间,借此机会总结一下GAMBIT.ICEM和HYPERMESH这三款软件作为fluent的前处理软件时,划分耦合面网格时的方法,由于前两者大家用的比较多,只做大概叙述,主要详述后者,大家谁有别的或者更好的办法解决这类问题的,可以拿出来分享一下. 模型:简单的一个圆柱发热体,四周充满水的流固模型,如图1所示,导入前处理软件时是两个体. 图1 GAMBIT:创建方法如图2所示.…

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. Have you met this question in a real interview? Yes Example Given [0,1,0,2,1,0,1,3,2,1,2,1], return…
