Strengths:

• The student has correctly implemented both data structures with the required time and space complexity.
• The code is well-commented and easy to understand.
• The student has handled edge cases appropriately, such as checking for empty stacks in the queue and handling null values in the hashmap.

Areas for Improvement:

• In the queue's peek method, the logic can be simplified by reusing the pop method's approach (transferring elements from in_stack to out_stack when out_stack is empty). This would make the code more concise and maintainable.
• The hashmap implementation could benefit from a more detailed explanation of the double hashing technique used, especially why the secondary array size is 1001 for main_index 0.
• The student should ensure consistency in variable naming (e.g., inSt vs. in_stack) to follow a single naming convention.
