#11 - Container With Most Water

Medium • View on LeetCode • View on GitHub

Problem Description

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.

Solution

/**
 * @param {number[]} height
 * @return {number}
 */
var maxArea = function(height) {
  let maxArea = 0;

  for (let left = 0, right = height.length - 1; left < right;) {
    maxArea = Math.max(
      maxArea,
      Math.min(height[left], height[right]) * (right - left)
    );

    if (height[left] < height[right]) {
      left++;
    } else {
      right--;
    }
  }

  return maxArea;
};
