Your solution for "Find First and Last Position of Element in Sorted Array" is well-implemented. Here are some strengths and suggestions:

Strengths:

• You correctly used two separate binary search functions to find the first and last occurrence, which is an efficient approach.
• The code is clean and well-commented, making it easy to understand.
• You handled edge cases such as an empty array and target not in range.

Areas for Improvement:

• In the initial check, you can use nums[-1] to get the last element instead of nums[len(nums)-1] for brevity.
• Consider adding a docstring for the main function searchRange to describe its purpose and parameters.
• Although your initial range check is correct, note that if the array is very large, it might be slightly faster to skip this check and let the binary search handle it, as the binary search is O(log n) and the check is O(1). However, this is a minor point and your approach is acceptable.

Overall, your solution is correct and efficient. Keep up the good work!
