    1941 - Check if All Characters Have Equal Number of Occurrences\.

    Easy

    Given a string s, return true if s is a good string, or false otherwise.

    A string s is good if all the characters that appear in s have the same number of occurrences (i.e., the same frequency).

    Example 1:

    Input: s = "abacbc"

    Output: true

    Explanation: The characters that appear in s are 'a', 'b', and 'c'. All characters occur 2 times in s.

    Example 2:

    Input: s = "aaabb"

    Output: false

    Explanation: The characters that appear in s are 'a' and 'b'. 'a' occurs 3 times while 'b' occurs 2 times, which is not the same number of times.

    Constraints:

    • 1 <= s.length <= 1000

    • s consists of lowercase English letters.
