题目大意是提供n个非负整数,a1,...,an,可以将其理解为多个边界(垂直的线段),其中ai处于x坐标i处,并且ai代表的线段高度即为ai的值.要求我们取这样的i与j,使得ai与aj以及x坐标轴围成的碗状物能容纳面积最多的水(即abs(i-j)*min(ai,aj)最大). 最简单的方案就是暴力枚举: res= -1, maxl = 0, maxr = 0 for(i=0; i < n; i++) for(j = i + 1; j < n; j++) res = max(abs(i-j)*m…

前言 这题非要说贪心的话也算是吧,不过最主要的特征还是双指针.LC的题好像不少都是扔倆头尾指针然后遍历一遍完事儿的.这道题倒是“短板效应”的不错体现了. 题目 题目链接 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…

前言 难怪LeetCode OJ在找工作时被很多人推荐,发现了这道最大蓄水题目就是美团的笔试最后一道题,当时我霸笔只有着一道题目没有答出来,因此也就没有获得面试机会,可惜了 题目 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 li…

本来写的题目不是这个,而是字符串匹配,考虑了很多情况写了很久最后看了solution,发现可以用动态规划做.感觉被打击到了,果断先放着重新写一个题,后面心情好了再重新写吧,难过.每天都要被LeetCode打击一次.自“抱”自“泣”,逻辑推理能力太差了. 题目: Given n non-negative integers a1, a2, ..., an, where each represents a point at coordinate (i, ai). n vertical lines ar…
