Good String Determination

Given a string containing only lowercase English letters, a string is considered good if every distinct character in the string occurs the same number of times. For example, the string "aabb" is good since both 'a' and 'b' occur twice, whereas "aabbbb" is not good because the characters occur a different number of times.

If the string is empty, it is considered good.
