刚开始用暴力循环
class Solution:
def maxArea(self, height: List[int]) -> int:
n=len(height)
area=[]
for x1 in range(n):
for x2 in range(x1+1,n):
width_rec= x2-x1
if height[x1]>height[x2]:
height_rec= height[x2]
else:
height_rec= height[x1]
#
area.append(width_rec*height_rec)。
return max(area)
会超时,看了题解是要用双指针的方法,从两边开始移动,现在时间比较紧,晚点自己写一遍原理证明,加强印象。
官方题解
class Solution:
def maxArea(self, height: List[int]) -> int:
l, r = 0, len(height) - 1
ans = 0
while l < r:
area = min(height[l], height[r]) * (r - l)
ans = max(ans, area)
if height[l] <= height[r]:
l += 1
else:
r -= 1
return ans
