Xs and Os, Nobody Knows

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).
• Return True if the amount of x's and o's are the same.
• Return False if they aren't the same amount.
• The string can contain any character.
• When "x" and "o" are not 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

Notes

• Remember to return True if there aren't any x's or o's.
• Must be case insensitive.
