Container With Most Water
Updated Jan 31, 2026
Problem
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.
Constraints
n == height.length
2 <= n <= 10^5
0 <= height[i] <= 10^4
Examples
Example 1
Input:
height = [1,8,6,2,5,4,8,3,7]
Output:
49
The max area is between index 1 and 8, with height min(8,7)=7 and width 7, giving 49.
Example 2
Input:
height = [1,1]
Output:
1
Function Signature
def maxArea(self, height: list[int]) -> int
How to Submit
Implement a Solution class with a maxArea method.
Your method will be called with the input parameters and should return the answer.
