#Leetcode# 11. Container With Most Water

https://leetcode.com/problems/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 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.

 

The above vertical lines are represented by array [1,8,6,2,5,4,8,3,7]. In this case, the max area of water (blue section) the container can contain is 49.

 

Example:

Input: [1,8,6,2,5,4,8,3,7]
Output: 49

代码：

class Solution {
public:
    int maxArea(vector<int>& height) {
        int N = height.size();
        int maxx = 0, ans = 0;
        for(int i = 0; i < N - 1; i ++) {
            for(int j = i + 1; j <= N - 1; j ++) {
                maxx = min(height[i], height[j]);
                ans = max(ans, (j - i) * maxx);
            }
        }
        return ans;
    }
};
