Frequent Words with Mismatches: 5-mer with 1 mismatch allowed

Algorithm Description

The "Frequent Words with Mismatches" algorithm identifies the most frequent k-mers (substrings of length k) within a given text, allowing for a specified number of mismatches (differences between characters). This is particularly useful in bioinformatics for finding motifs in DNA sequences that are not exactly identical but share a common pattern. The algorithm works by generating all possible k-mers with up to d mismatches for each k-mer in the text, then counting the occurrences of these k-mers. The k-mers with the highest frequencies are then identified as the most frequent patterns with mismatches.
