Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
