• The student's solution for the missing number problem is well-implemented and correct. The binary search approach is efficient and correctly identifies the missing number.
• The comments and variable names are clear, making the code easy to understand.
• The unrelated min-heap implementation (Problem2.java) should not be included in the submission for this problem, as it does not pertain to the task at hand.
• For future submissions, ensure that only the relevant code is included to avoid confusion.
