标签：end nums python start ans return total 巧用
在return里写条件语句
return 0 if ans == n + 1 else ans
参考
力扣：长度最小的子数组
class Solution:
def minSubArrayLen(self, s: int, nums: List[int]) -> int:
if not nums:
return 0
n = len(nums)
ans = n + 1
start, end = 0, 0
total = 0
while end < n:
total += nums[end]
while total >= s:
ans = min(ans, end - start + 1)
total -= nums[start]
start += 1
end += 1
return 0 if ans == n + 1 else ans
