Interview Problem: Find Missing Number in a sorted array (Problem1.java)

Strengths:

• Excellent implementation that matches the reference solution's approach
• Added valuable edge case handling for missing numbers at positions 1 and n+1
• Clear and informative comments explaining the binary search logic
• Proper use of the formula arr[low] + 1 for the final answer
• Good Java coding practices with static method and proper class structure

Areas for Improvement:

• The solution is already well-optimized. One minor consideration: the edge case checks could theoretically be integrated into the binary search loop for a more unified approach, but the current separate handling is clear and correct.
• Consider adding a few test cases in the main method to demonstrate the solution works for different scenarios (missing at start, middle, and end).

VERDICT: PASS

Interview Problem: Design Min Heap (Problem2.java)

Strengths:

1. Clean and well-organized code structure that mirrors the reference solution
2. Comprehensive comments explaining time and space complexity
3. Proper encapsulation with private helper methods
4. Correct implementation of all heap operations
5. Good variable naming and readable code style

Areas for Improvement:

1. The printHeap method could be enhanced to show more levels of the heap for better visualization
2. Consider adding bounds checking in helper methods for robustness
3. The isLeaf method logic is correct but could be simplified to i >= size / 2

Overall, this is a solid implementation that correctly solves the problem and matches the reference solution in both approach and complexity.

VERDICT: PASS
