로그앤 2023. 10. 12. 16:59

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.

Example 1:
Input: height = [1,8,6,2,5,4,8,3,7]
Output: 49
Explanation: 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 2:
Input: height = [1,1]
Output: 1

class Solution:
    def maxArea(self, height: List[int]) -> int:
        L,R = 0, len(height)-1
        res = 0
        while L < R:
            area = (R-L) * min(height[L],height[R])
            res = max(res,area)
            if height[L] < height[R]:
                L+=1
            else:
                R-=1
        return res
