• The solution for Problem1 is well-implemented and handles all edge cases correctly. The binary search logic is clear and efficient.
• The comments are helpful, but it would be better to explain the logic in the comments for the binary search methods (bs1 and bs2) to make it clearer for someone reading the code.
• The variable names could be more descriptive. For example, bs1 and bs2 could be renamed to binarySearchFirst and binarySearchLast to match the reference solution and improve readability.
• The solution for Problem2 and Problem3 are not part of the Binary-Search-2 problem, so they should not be included in the evaluation for this problem.
