• Strengths:
  • The logic for finding the first and last occurrences is correctly implemented using binary search.
  • The code is modular and easy to follow.
  • Edge cases are handled appropriately.
• Areas for Improvement:
  • Remove the 'self' parameter from the helper functions since they are not class methods.
  • Consider adding comments to explain the binary search logic more clearly, especially for the conditions that check for the first and last occurrences.
  • The variable names could be more descriptive (e.g., 'l' and 'r' could be 'left' and 'right').
