Note: This lab should be completed in small groups of 2-3.
This lab will help you gain more practice with searching.
You are given 3 things to sort. Write your solutions on a whiteboard, showing the steps for each search. Take photos of the answers. For example,
1, 2, 3, 4, 5, 6, 7, 8, 9, 10
To find the number 7, the steps are:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10
6, 7, 8, 9, 10
6, 7, 8
7
3, 5, 6, 8, 11, 12, 14, 15, 17, 18 || Find 16
1, 4, 6, 7, 12, 13, 15, 18, 19, 20, 22, 24 || Find 20
-22, 7, 33, 12, 0, 0, -9, 66, 94, 103, 34, 54, 12, 54, 80, 90, 2 || Find 34
Bonus:
With the following set, show the steps of the binary search as well as the sorting beforehand. Sort in any way you feel is best:
94, 103, 34, 54, 12, 54, 80, 90, 2 || Find 80
Bonus #2
In either pseudocode or java, write the algorithm for binary search recursively. Take a pic of it, or save it in a file.
Pictures of each of the practice problems.
