Show hintHide hint
Think about how you compare items to keep them ordered.
Question 2.
What is the time complexity of the merge operation?
Show hintHide hint
Remember how many comparisons are made.
3Question 3.
What is the primary purpose of the merge operation in merge sort?
- To compare two lists

4Question 4.

- True
- False
Show hintHide hint
Consider how the merging process works.
Question 5.
Imagine you are tasked to implement a merge function that does not create a new array. Describe your approach, including possible challenges and outcomes.
Show hintHide hint
Consider the implications of 'in-place' operations and how they affect time complexity.
Question 6.
Devise an algorithm that performs both the intersection and the difference of two sorted lists. Provide the pseudocode for each operation.
Show hintHide hint
Think about how the conditions change depending on the results desired: intersection versus difference.
