1. Correctness:

• Problem 1 (Search a 2D Matrix): The solution correctly implements binary search on a flattened 2D matrix. It handles edge cases well (empty matrix or matrix with empty rows).
• Problem 2 (Search in Rotated Sorted Array): The logic is mostly correct but has a bug. Using nums.index(target) defeats the purpose of binary search and makes it O(n) in worst case. The second if should be an elif to avoid unnecessary checks.
• Problem 3 (Search in Infinite Sorted Array): The solution correctly implements the two-phase approach (finding bounds then binary search) and handles the ArrayReader interface properly.

2. Time Complexity:

• Problem 1: Correctly identified as O(log(m*n))
• Problem 2: Claimed O(log n) but due to the index() call, it's actually O(n)
• Problem 3: Correctly identified as O(log n)

3. Space Complexity:

• All problems correctly identified as O(1) space complexity.

4. Code Quality:

• Generally good with clear comments and structure.
• Variable names are appropriate.
• The bug in Problem 2 and the redundant condition check are the main quality issues.
• Could benefit from more consistent docstring formatting across files.

5. Efficiency:

• Problem 1 is optimal.
• Problem 2 could be made more efficient by removing the index() call and using the binary search properly.
• Problem 3 is optimal.

Areas for Improvement:

• Remove the index() call in Problem 2 and properly implement binary search.
• Change the second if to elif in Problem 2 to avoid redundant checks.
• Consider adding more edge case tests (e.g., single element arrays, target not present, etc.).
• Make docstrings more consistent across files.
