Leetcode Solutions

Brute Force with Bitmasking

  1. Iterate over all possible combinations of people's statuses using a bitmask from 0 to 2^n - 1.
  2. For each combination, check if it is valid by iterating over all people and their statements.
  3. If a person is assumed to be good (bit is 1), then all their statements must be consistent with the current combination.
  4. If any statement by a good person contradicts the combination, the combination is invalid.
  5. If the combination is valid, count the number of good people (number of 1s in the bitmask).
  6. Keep track of the maximum count of good people found in a valid combination.
  7. Return the maximum count after checking all combinations.
