14.1.5. Applications of Merge Operation

Try these first

1. 1.

   What is the time complexity of the merge operation?

   Hint

   Think about how many total elements are being merged.

2. 2.

   Define the union of two sets.

   Hint

   It’s like merging but with a focus on both sets.

5. 5.

   Design a merge function that can find the intersection of two sorted lists using the merging technique.

   Hint

   Think about how you would compare and skip over non-matching items.

6. 6.

   Describe a real-world scenario where merging sorted lists efficiently provides significant benefits. What would be the challenges?
