Algorithms question 11
Insertion sort is applied to [5, 2, 4, 6, 1, 3]. What does the array look like after the first 2 passes (i.e. after inserting the elements at index 1 and index 2)?
- [2, 5, 4, 6, 1, 3]
- [2, 4, 5, 6, 1, 3]
- [1, 2, 4, 6, 5, 3]
- [2, 4, 5, 1, 6, 3]
Answer and explanation
Answer: B. [2, 4, 5, 6, 1, 3]
Explanation: Pass 1 inserts 2 before 5: [2, 5, 4, 6, 1, 3]. Pass 2 inserts 4 between 2 and 5: [2, 4, 5, 6, 1, 3].
