It is an algorithm that iterates entirely through a dataset exactly two times to achieve the final result.
It is O(2N), which simplifies to O(N) Linear Time in Big O notation, making it highly efficient.
During the second pass, the condition explicitly checks that the current number is strictly less than the maximum, automatically bypassing any duplicates of the max.
