Interview Problem : Two elements sum to target (Problem1.py)

Strengths:

• Excellent implementation of the hash map approach, which is the optimal solution for this problem
• Well-documented code with time/space complexity analysis
• Clean, readable code with meaningful variable names
• Comments effectively explain the logic
• Includes LeetCode status and problem URL for reference

Areas for Improvement:

• Using map as a variable name shadows Python's built-in map function. Consider using num_map or hash_map instead for better practice
• The solution could include a brief docstring explaining the method's purpose and parameters
• Could add a type hint for better code documentation (e.g., def twoSum(self, nums: List[int], target: int) -> List[int]:)

Minor Note:

• The problem states "exactly one solution exists," but the code doesn't explicitly handle edge cases. However, this is acceptable since the problem guarantees exactly one solution.

VERDICT: PASS

Interview Problem: 0-1 Knapsack Problem (Problem2.py)

Strengths:

• Demonstrates strong understanding of DP optimization by using 1D array instead of 2D
• Excellent code documentation and readability
• Correctly implements the right-to-left traversal pattern essential for 0-1 knapsack
• Clean, concise implementation

Areas for Improvement:

• The time complexity notation could be more precise: O(n*W) rather than O(W) to accurately reflect the nested loop structure
• Could add input validation (e.g., checking that val and wt arrays have the same length)
• Consider edge case handling for empty arrays or zero capacity

VERDICT: NEEDS_IMPROVEMENT
