Question 1.
What does linear search focus on when trying to find an element in an array?
Show hintHide hint
Think about how you would manually search for a number on a list.
Question 2.
What is the primary requirement for binary search to function correctly?
Show hintHide hint
Consider how binary search determines where to look next.
3Question 3.
What is the primary advantage of binary search over linear search?
- It's faster since it uses less time on average.
- It's easier to implement.
- It's better for unsorted arrays.
Show hintHide hint
Remember the time complexities we've discussed.
4Question 4.
True or False: Linear search can be applied to both sorted and unsorted arrays.
- True
- False
Show hintHide hint
Think about the general approach of linear search.
Question 5.
You are given an unsorted array of integers: [14, 3, 7, 8, 1, 2]. Design a function to apply linear search to find the index of number 7. What is the expected output and explain your steps?
Show hintHide hint
Iterate over the array one element at a time.
Question 6.
Given a sorted array [1, 3, 5, 7, 9, 11] and needing to find the number 8 using binary search, outline the steps of the algorithm.
Show hintHide hint
Keep applying the midpoint logic and eliminate half of the search space each time.
