Quick Overview

This question evaluates a candidate's ability to combine bitmasking with backtracking or subset enumeration to maximize a constraint over combinations of strings. It tests practical application of state-space search and character-set tracking, a common category in coding interviews assessing algorithmic problem-solving under small input bounds.
