• Strengths:
  • The solution correctly implements the prefix sum and hash map approach.
  • The code is well-commented and easy to understand.
  • The time and space complexity are optimal.
• Areas for Improvement:
  • Instead of storing arrays of indices in the hash map, consider storing counts of how many times each cumulative sum has occurred. This simplifies the logic and reduces memory usage.
  • The initial comment could be more detailed to explain the intuition behind the approach, especially why storing counts would be more efficient.
  • The variable name currAssignedVal could be more descriptive, such as indices or sumIndices.
