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.
Yes, it is a great intermediate solution. However, after presenting it, the interviewer will almost certainly ask you to optimize it into a single pass.
