  class Solution:
      def reverseString(self, s: List[str]) -> None:
          """
          Do not return anything, modify s in-place instead.
          """
          length = len(s)
          for i in range(length // 2):
              if s[i] == s[length - 1 - i]:
                  continue
              s[i], s[length - 1 - i] = s[length - 1 - i], s[i]
