![]() Here the algorithm is trying to search for a pattern of P in the text T. ![]() The below pseudo-codes explain the string matching logic. As soon as a mismatch is found, the substring’s remaining character is dropped, and the algorithm moves to the next substring. Brute force String matching compares the pattern with the substring of a text character by character until it gets a mismatched character. If all the characters in the pattern are unique, then Brute force string matching can be applied with the complexity of Big O(n) where n is the string’s length. ![]() The will be no difference between the worst and best case as the no of swap is always n-1. Here the problem is of size ‘n’, and the basic operation is ‘if’ test where the data items are being compared in each iteration. The above statement can be written in pseudo-code as follows. After each iteration over the list, it replaces the smallest element to the top of the stack and starts the next iteration from the second smallest data in the list. ![]() In the brute force sort technique, the data list is scanned multiple times to find the smallest element in the list.
