Leetcode Problem 229. Majority Element II

229. Majority Element II

Leetcode Solutions

Boyer-Moore Voting Algorithm for Finding Majority Elements

  1. Initialize two candidate variables and two counters to None and 0 respectively.
  2. Iterate through the array, updating the candidates and counters as follows:
    • If the current element is equal to one of the candidates, increment the corresponding counter.
    • If one of the counters is zero, set the corresponding candidate to the current element and reset the counter to one.
    • If the current element is different from both candidates, decrement both counters.
  3. After the first pass, initialize a list to hold the result.
  4. Perform a second pass to count the occurrences of the two candidates.
  5. If a candidate's occurrence is more than ⌊n/3⌋ times, add it to the result list.
  6. Return the result list.
