Given a string s consisting of some words separated by some number of spaces, return the length of the last word in the string.
A word is a maximal substring consisting of non-space characters only.
Example 1:
Input: s = "Hello World"
Output: 5
Explanation: The last word is "World" with length 5.
Example 2:
Input: s = " fly me to the moon "
Output: 4
Explanation: The last word is "moon" with length 4.
Example 3:
Input: s = "luffy is still joyboy"
Output: 6
Explanation: The last word is "joyboy" with length 6.
Constraints:
1 <= s.length <= 104
s consists of only English letters and spaces ' '.
There will be at least one word in s.
Python solution
class Solution:
def lengthOfLastWord(self, s: str) -> int:
length = 0
new_str = s.strip()
for i in range(len(new_str)):
if new_str[i] == " ":
length = 0
else:
length +=1
return length
