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: 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.
class Solution:
def maxArea(self, height: List[int]) -> int:
# ans = 0
# for l in range(len(height)):
# for r in range(l+1, len(height)):
# ar = (r-l) * min(height[l],height[r])
# ans = max(ans, ar)
# return ans
ans = 0
l, r = 0, len(height)-1
while l<r:
ar = (r-l) * min(height[l],height[r])
ans = max(ans, ar)
if height[l] < height[r]:
l+=1
else :
r -=1
return ans
