11. Container With Most Water

LeetCode

通过观察面积公式，如果我们想让面积最大，就要让(right_index - left_index)由最大值向0收敛，并且尽可能地提高Min(height[left_index], height[right_index])的“短板”。

class Solution {
    public int maxArea(int[] height) {
        int left = 0;
        int right = height.length - 1;
        int area = 0;
        while (left <= right) {
            area = Math.max(area, (right - left) * Math.min(height[left], height[right]));
            if (height[left] < height[right]) {
                left++;
            } else {
                right--;
            }
        }
        return area;
    }
}
