11. Container With Most Water

You are given an integer array height of length n. There are n vertical lines drawn such that the two endpoints of the ith line are (i, 0) and (i, height[i]).

Find two lines that together with the x-axis form a container, such that the container contains the most water.

Return the maximum amount of water a container can store.

Notice that you may not slant the container.

Input: height = [1,8,6,2,5,4,8,3,7]
Output: 49
Explanation: Look at below image

Solution

function maxArea(height: number[]): number {
    let start = 0;
    let end = height.length - 1;
    let max = 0;
    while (start < end) {
        max = Math.max(max, (end - start) * Math.min(height[start], height[end]))
        if (height[start] < height[end]) start++
        else end--
    }

    return max
}
