Implement a method to remove duplicates from an array while allowing at most two occurrences of each number.

• The student's solution is for a different problem (removing duplicates with at most k duplicates allowed) rather than merging two sorted arrays. It is important to carefully read and understand the problem statement before attempting to solve it.
• The code quality and efficiency are good for the problem the student addressed, but the solution does not match the reference problem.
• In the future, ensure that the solution aligns with the problem requirements. Double-check the problem statement and verify that the solution addresses the correct problem.
