Cuyamaca College CS-282 Intermediate Java Programming John Gerstenberg, Instructor Lab #8 Student Learning Outcomes  Algorithm analysis and implementation. Overview In real world software development, you will often “inherit” a software project from either a colleague or another programming team. Overall, the software may work but there are inefficient algorithms or other issues that require correction. In this exercise, you will be given a working program but you’ll need to implement a more efficient algorithm for one of its methods. Exercise 1: This exercise is based on exercise 22-3 on page 871. You are given a brute force version of a pattern matching algorithm called matchBruteForce(). Your task is to implement the match() method that will be O(n) time complexity. Do NOT use the String class indexOf() method. You may do this as a console application or you may use JavaFX. You are given starter code for this exercise. For a few quick points, what is the complexity of matchBruteForce(). To keep this quick and simple, put your answer and explanation in a comment in the code. Grading Criteria: Deliverable Time complexity of matchBruteForce() Match() method Java code 1 Points 3 Breakdown Correct result, answer explained at least briefly. 14 3 Coded, works, O(n) complexity Clean, easy to read, descriptive variable names, appropriate sue of constants and comments. // pseudocode for a match() method that is O(n) match(theString, pattern) i = 0 k = 0 pLen = length of pattern sLen = length of theString while i < sLen if k == pLen then return i - pLen else if (theString.charAt(i) == pattern.charAt(k)) then k = k + 1 // character matched else k = 0 // no match - reset and start over end end i = i + 1 end while if k == pLen then return sLen - pLen else return -1; ...
