Challenge Problems
Push your limits with challenges.
Question 1
Given two sorted arrays A = [1, 3, 5] and B = [2, 4, 6], write a function to merge them without using additional arrays.
💡 Hint: Think about how to use indexes of each array to insert elements directly.
Question 2
Create a visual representation of the merge sort algorithm applied to the array [12, 11, 13, 5, 6, 7]. Describe the merge steps as you go.
💡 Hint: Document each comparison during the merging process to illustrate the order.
