 Converts a string to camelcase.
 
-Break the string into words and combine them capitalizing the first letter of each word, using a regexp, `title()` and `lower`.
+Use `re.sub()` to replace any `-`,`_` or ` ` (space) with a space, using the regexp `r"(_|-)+"`.
+Use `title()` to capitalize the first letter of each word convert the rest to lowercase.
+Finally, use `replace()` to remove spaces between words.
 
 ```py
 import re
 
 def camel(s):
-  s = re.sub(r"(\s|_|-)+", " ", s).title().replace(" ", "")
+  s = re.sub(r"(_|-)+", " ", s).title().replace(" ", "")
   return s[0].lower() + s[1:]
