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.
