Create a function that returns a list of strings that are sorted alphabetically
"""
def sortList(someList):

"""
Create a function that takes a string, checks if it has the same number of "x"s
and "o"s and returns either True or False.
- Return a boolean value (True or False).
- The string can contain any character.
- When no x and no o are in the string, return True.

Examples:
- XO("ooxx") ➞ True
- XO("xooxx") ➞ False
- XO("ooxXm") ➞ True (Case insensitive)
- XO("zpzpzpp") ➞ True (Returns True if no x and o)
- XO("zzoo") ➞ False
