.
Solution
class Solution:
def lengthOfLastWord(self, s: str) -> int:
cnt = 0
if len(s) > 0:
lst = list(s.split(“ “))
for i in range(1, len(lst)):
tmp = len(lst[-i])
cnt = i
if tmp != 0:
return tmp
if len(s) == 1:
return len(s)
else:
return len(lst[-(cnt+1)])
else:
return -1
The performance of my code is shown in the above picture.
Thanks for reading my solution. Appreciate your claps.
