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 the line i
is at (i, ai)
and (i, 0)
. Find two lines, which, together with the x-axis forms a container, such that the container contains the most water.
Notice that you may not slant the container.
Example 1:

Input: height = [1,8,6,2,5,4,8,3,7] Output: 49 Explanation: 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 2:
Input: height = [1,1] Output: 1
Example 3:
Input: height = [4,3,2,1,4] Output: 16
Example 4:
Input: height = [1,2,1] Output: 2
Constraints:
n == height.length
2 <= n <= 105
0 <= height[i] <= 104
Solution:
/**
* @param {number[]} height
* @return {number}
*/
var maxArea = function(height) {
let len = height.length;
let l = 0
let r = len - 1;
let maxA = 0;
while (l < r) {
let minH = Math.min(height[l], height[r]);
maxA = Math.max(maxA, minH * (r - l));
if (height[l] < height[r]) {
l++;
} else {
r--;
}
}
return maxA;
};
