We will calculate areas for all pair of bars and return maximum value. The first thing we should realize is that the amount of water contained is always going to be a rectangle whose area is defined as length * width. The above vertical lines are represented by array [1,8,6,2,5,4,8,3,7]. Return the maximum amount of water a container . 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. For example if [4,3,2,6] is the given heights array, we start by comparing the 0th and 1st index elements, i.e. Are you sure you want to hide this comment?

This tutorial is only for Educational and Learning purpose. ExamplesArray : [ 2, 5, 4, 3, 1]Output : 6 unitsThe maximum water can be stored between (5,3) vertical Lines.Output= 6 =min(5,3)*(distance between both vertical lines (2)). Check if Array Is Sorted and Rotated, Initialize the left pointer to 0 and the right pointer to the length of the array - 1, Loop through the array while the left pointer is less than the right pointer, Calculate the area by multiplying the minimum of the height of the left and right pointer by the difference of the right and left pointer, Update the maxArea by comparing the maxArea and the area, If the height of the left pointer is less than the height of the right pointer, increment the left pointer, else decrement the right pointer. [LeetCode] 11. Container With Most Water (Java) - Continue the loop until the pointers meet or cross each other. Then we scan from both sides. class Solution { public int maxArea(int[] nums) { int max = Integer.MIN_VALUE; int n = nums.length; int i = 0; int j = n - 1; while(i < j) { // The aim is to maximize the area formed between the vertical lines. Given n non-negative integers a1, a2, ., an, where each represents a point at coordinate (i, ai). Therefore, the steps will be something like this .

Given n non-negative integers a1, a2, , an , where each represents a point at coordinate (i, ai). Just looking at the visual, however, it's obvious that we can skip the next few lines because they're already underwater, so we should go to the first line that's larger than the current water height: This time, it doesn't look like we made much of a gain, despite the fact that the water level rose a bit, because we lost more in width than we made up for in height. How to handle repondents mistakes in skip questions? n vertical lines are drawn such that the two endpoints of line i is at (i, ai) and (i, 0). Hence, for 8 to be in the answer, other line should be 10. In order to use an efficient solution to find the maximum water we can store in a container, we will start with two vertical lines, first and last, and check how much water can be stored. 3. My solution: Run a nested loop i = 0 till i = N and j = i + 1 till N. Keep incrementing the pointer pointed at smaller height towards each other.
