Strengths:

• Excellent implementation of binary search variations for different problem types
• Clear and concise code with good comments
• Correct time and space complexity analysis
• Proper handling of edge cases (empty arrays, out of bounds checks)

Areas for Improvement:

• In Problem3_SearchInfiniteSortedArray.py, consider adding a comment explaining why you're using try-except (since ArrayReader might not raise IndexError but return a special value instead)
• The problem titles in the filenames could be more specific (e.g., "SearchInRotatedSortedArray" instead of "SearchRotatedSortedArray")
• Consider adding docstrings to the methods for better documentation
