Show hintHide hint
Think about how cards are sorted.
Question 2.
What is the worst-case time complexity of insertion sort?
Show hintHide hint
Consider the scenario of sorting a completely reversed list.
3Question 3.
What is the main process of insertion sort?
- A. Sorting by selection

Show hintHide hint
Remember how we sort cards.
4Question 4.
True or False: Insertion sort is more effective on large, unsorted datasets than on nearly sorted data.
- True
- False
Show hintHide hint
Think about the efficiencies we discussed.
Question 5.
Given an array of integers [5, 2, 9, 1, 5, 6], illustrate each step of the insertion sort process.
Show hintHide hint
Visualize the process as inserting numbers one by one into an already sorted list.
Question 6.
Analyze the effectiveness of using insertion sort on a dataset of 1,000 elements that is nearly sorted. What is the expected time complexity?
Show hintHide hint
Think about the efficiency of comparisons in nearly sorted arrays.
