How does Boyer Moore Algorithms work on a conceptual level?


How does a Pattern traverse along a provided Text?

 

Is it...

Case 1: Mismatch Character doesn't belong in pattern, skip at Mismatch location in text by full length

 

Case 2: Mismatch character is earlier in pattern, skip to rightmost occurrence of character in pattern.

 

 

Am I missing anything or is this understanding wrong?

Expert Solution
Step 1: Providing Introduction

A powerful string searching method that effectively finds instances of a pattern within a text is the Boyer-Moore algorithm. When there is a mismatch between the pattern and the text, it can intelligently pass over certain parts of the text, which is how it works. Let's examine Boyer-Moore's core ideas in order to comprehend how it conceptually functions.

Please refer to the following steps for the complete solution to the problem above.
