WebKMP Algorithm – data find out the suffix and prefix which are common. In this case ‘ac’ is the string which is the longest common substring such that it is the suffix and prefix both. Step 3: We can see “acbac” matches with the given text as since they have matched then only we have reached the mismatched character ‘d’. WebKMP algorithm is used to find a "Pattern" in a "Text". This algorithm campares character by character from left to right. But whenever a mismatch occurs, it uses a preprocessed … extended stay america perimeter park south
