+# Length of Last Word
+
+# Problem 58
+# 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.
+

+  def length_of_last_word(self, s: str) -> int:
+    length = 0
+    isWord = False

+        length += 1
