Question 1

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.

💡 Hint: Remember the time complexities we've discussed.

Question 2

True or False: Linear search can be applied to both sorted and unsorted arrays.

  • True
  • False

💡 Hint: Think about the general approach of linear search.

Challenge Problems

Push your limits with challenges.

Question 1

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?

💡 Hint: Iterate over the array one element at a time.

Question 2

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.

💡 Hint: Keep applying the midpoint logic and eliminate half of the search space each time.
