# Prompt

Given a string containing only the characters `x` and `y`, find whether there are the same number of `x`s and `y`s.

    balanced("xxxyyy") => true
    balanced("yyyxxx") => true
    balanced("xxxyyyy") => false
    balanced("yyxyxxyxxyyyyxxxyxyx") => true
    balanced("xyxxxxyyyxyxxyxxyy") => false
    balanced("") => true
    balanced("x") => false

## Optional bonus

Given a string containing only lowercase letters, find whether every letter that appears in the string appears the same number of times. Don't forget to handle the empty string (`""`) correctly!

    balanced_bonus("xxxyyyzzz") => true
    balanced_bonus("abccbaabccba") => true
    balanced_bonus("xxxyyyzzzz") => false
    balanced_bonus("abcdefghijklmnopqrstuvwxyz") => true
    balanced_bonus("pqq") => false
    balanced_bonus("fdedfdeffeddefeeeefddf") => false
    balanced_bonus("www") => true
    balanced_bonus("x") => true
    balanced_bonus("") => true

Note that `balanced_bonus` behaves differently than `balanced` for a few inputs, e.g. `"x"`.
