Container With Most Water
Description
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 container, such that the container contains the most water.
Note: You may not slant the container and n is at least 2.
给出n个点,它们与X轴有n条垂线,每两条垂线与X轴形成的U型容器,找出最大“容积”(面积)
Solution
