| Topic | Sorting Algorithms |
| Type | Deducing Original List Properties |
| Difficulty | Moderate -0.5 This is a straightforward D1 question requiring students to trace through a sorting algorithm (likely bubble sort or quick sort) in reverse to deduce properties of the original list. While it requires careful systematic work through multiple passes, it's a standard algorithmic procedure with no conceptual difficulty beyond following the algorithm's rules mechanically. |
