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.
