Search inside a Rotated Sorted Array (Sample.java)

Strengths:

• The solution for Problem 2 (rotated array search) is correctly implemented and matches the reference solution
• Good use of low + (high - low) / 2 to prevent integer overflow
• Clear comments explaining the approach
• Proper handling of edge cases

Areas for Improvement:

• The submission includes solutions for problems that weren't asked (Problem 1 and Problem 3)
• For the actual problem, the solution is complete and correct - no major improvements needed
• Minor: Could add early return for empty array edge case (though constraints say length >= 1)

VERDICT: PASS

Search Inside a Sorted Array whose Length is unknown

Strengths:

1. The solution correctly implements the exponential search + binary search pattern required for unknown-length arrays
2. Good use of comments explaining the approach
3. Proper handling of edge cases (returning -1 when target not found)
4. Clean and readable code structure

Areas for Improvement:

1. The submission includes solutions for 3 different problems, but only Problem 3 is relevant to the given problem. Focus on submitting only the solution for the specific problem.
2. Consider adding comments explaining the exponential expansion phase specifically (why we double high until it's >= target)

VERDICT: PASS

Search a 2D Matrix

Strengths:

1. All three solutions demonstrate solid understanding of binary search variations
2. Code is well-commented with clear approach explanations
3. Proper use of mid = low + (high - low) / 2 to prevent integer overflow
4. Consistent naming conventions and code structure
5. Correct handling of edge cases (empty returns, proper loop conditions)

Areas for Improvement:

1. Problem 2 has a minor formatting issue - the closing brace for the while loop appears to be missing in the provided code (though this might be a copy-paste artifact)
2. Consider adding more inline comments for the index calculations in Problem 1 to make the logic clearer for readers

VERDICT: PASS
