Tag: Array, Two Pointers

Difficulty: Medium

/*11. Container With Most Water (Medium)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.*/class Solution {public:int maxArea(vector<int>& height) {int water = 0, i = 0, j = height.size() - 1;while (i < j) {int h_min = min(height[i], height[j]);water = max(water, h_min * (j - i));while (height[j] <= h_min && i < j) {                j--;            }            while (height[i] <= h_min && i < j) {                i++;            }        }        return water;    }};
