Description

Given a DNA string pattern and an integer $d$, find the collection of strings that are within a $d$-neighborhood of the given pattern. A $d$-neighborhood is the set of all $k$-mers whose Hamming distance from the pattern is at most $d$.

Parameters

$n$: length of string

$d$: neighborhood distance threshold

$\sigma$: size of alphabet
