Hints
Hint 1
Consider using a hash map to count occurrences of each element, then find the element with the highest count.
Hint 2
Optimize space by tracking only the current candidate and its count, updating them as you iterate through the array.
Hint 3
Leverage the fact that the majority element appears more than ⌊n/2⌋ times to validate the candidate at the end of the iteration.
