1224. Maximum Equal Frequency

Leetcode Solutions

Frequency Counting and Prefix Analysis

  1. Initialize two hashmaps: elementFrequency to store the frequency of each element, and frequencyCount to store the count of frequencies.
  2. Initialize variables maxFrequency to keep track of the maximum frequency and result to store the length of the longest valid prefix.
  3. Iterate through the array, updating elementFrequency and frequencyCount for each element.
  4. After each update, check if the current prefix satisfies one of the conditions for a valid array after removing one element.
  5. Update result if the current prefix is valid.
  6. Return result as the final answer.
