For JAVA.
Transcribed Image Text:Write methods that implement linear, binary, and recursive binary search.
Have both methods display the value searched for, and the number of iterations needed to find
the value. You will need to add System.out.println() statements just before both return
statements for each algorithm. You will also need to add some kind of counter to track
iterations.
To test this, create an array: (0, 1, 2, 3, 4, 5, 6, 7, 8, ...) of at least 100 values.
Search for the following values in the array, first using linear search, then using binary search.
Values:
5
10
17
20
25
50
83
n, where n is the length of the array. (If the array has 100 values, search for the number 100.)
-1
Sample output should look like this (be sure to include binary and binary recursive as well):
Testing search with an array of length 100
Testing linear search:
Linear search needed 5 iterations to find 5.
Linear search needed 10 iterations to find 10.
Linear search needed 17 iterations to find 17.
Linear search needed 20 iterations to find 20.
Linear search needed 25 iterations to find 25.
Linear search needed 50 iterations to find 50.
Linear search needed 83 iterations to find 83.
Linear search needed 100 iterations and FAILED to find 100.
Linear search needed 100 iterations and FAILED to find -1.
