11. Container With Most Water

Given n non-negative integers a, a, …, a, where each represents a point at coordinate (i, a). n vertical lines are drawn such that the two endpoints of line i is at (i, a) 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

/**
 * @param {number[]} height
 * @return {number}
 */
var maxArea = function(height) {
    let max = 0;
    for (let i = 0, j = height.length - 1; i < j;) {
        let cur = (j - i) * Math.min(height[i], height[j]);
        max = Math.max(cur, max);
        height[i] < height[j] ? i++ : j--;
    }
    return max;
};
