Find the second minimum element in an array using an optimized approach with fewer than 2n comparisons.
AI-Expanded — inferred from the question title, not from the original candidate report
Given an unsorted array of $n$ distinct integers, design an algorithm to identify the second smallest element using fewer than $2n$ comparisons. Your solution should efficiently track the minimum and second minimum values in a single pass or through a tournament-style comparison structure to minimize the total number of operations.
