Reverse String

Input: s = ["h","e","l","l","o"]

Output: ["o","l","l","e","h"]

It's really simple in python

In our thinking the mathod of Reverse String is

return: s [::-1]

But it's didn't work in the Leetcode.

WTF!!!!!! Wrong Answer

Our except answer

I really confuse. But When I goolge the it why it didn't work. You may reset your memory in ans. Because the leetcode use the memory so your result didn't work.

class Solution:

def reverseString(self, s: List[str]) -> None:

"""

Do not return anything, modify s in-place instead.

"""

s[:] = s [::-1]

return s [::-1]

I reset my memory in the leetcode
