/* Container With Most Water
 *
 * @param {number[]} height
 * @return {number}
 *
 * 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.
