Brute Force Algorithm: String Matching Problem Solutions, Study notes of Web Programming and Technologies

Adamson University (AU)Web Programming and Technologies

Data Structures and AlgorithmsString Matching AlgorithmsBrute Force Algorithm

Solutions to various string matching problems using the Brute Force Algorithm. Each problem involves finding a specific pattern in a given text. The algorithm is demonstrated step-by-step, with the number of comparisons required to find the pattern indicated. The document concludes with the total number of comparisons made for each problem.

What you will learn

How many comparisons are needed to find the pattern 'all' in the text 'BlieveInYourselfAndAllThatYourAre'?
How many comparisons are needed to find the pattern '11001010' in the text '10100011011001010111011'?
How many comparisons are needed to find the pattern 'dove' in the text 'THEQUICKBROWNFOXJUMPDOVERTHELAZYDOG'?
