Master this problem using the Strings pattern.
When approaching Guess the Word, look for key problem signals that suggest using the Strings pattern. Focus on reducing redundant iterations, maintaining state invariant, and optimizing space-time complexity.
Key Invariant
Maintain optimal range bounds or hash frequency state during traversal.
Expected Complexity
Time: O(N) or O(N log N) | Space: O(1) to O(N)
