Let's understand the implementation of the Boyer-Moore algorithm. Initially, we have the text string and the pattern. After initializing the variables, we start with a while loop that starts by comparing the last character of the pattern to the corresponding character of the text.
Then, the characters are compared from right to left by the use of the nested loop from the last index of the pattern to the first character of the pattern. This uses range(len(pattern)-1, -1, -1).
The outer while loop keeps tracks of the index in the text string while the inner for loop keeps track of the index position in the pattern.
Next, we start comparing the characters by using pattern[j] != text[i+j]. If they are mismatched, ...
