Your solution is correct and efficient, meeting the problem requirements. Well done! Here are a few points to consider for improvement:

• Integer Overflow: When calculating the midpoint in binary search, it's safer to use mid = begin + (end - begin) / 2 instead of (begin + end) / 2. Although in Java the maximum array size is around 2^31-1, which would not cause overflow in this context (since begin and end are indices), it is a good habit to use the safer formula to avoid potential issues in other languages or contexts.

• Optimization for Last Occurrence Search: You can optimize the search for the last occurrence by starting from the first occurrence index (if found) rather than from the beginning of the array. This might reduce the number of comparisons in some cases, though the overall complexity remains O(log n). For example, in the reference solution, the last occurrence search starts from first (the index of the first occurrence) instead of 0.

• Consistency: In your other solutions (like for "Find the Minimum in Rotated Sorted Array" and "Find the Peak Element"), you used the safer midpoint calculation. It would be consistent to do the same here.

Overall, your code is clean and well-commented. Keep up the good work!
