Hashing is used to index and retrieve items in a database because it is faster to find the item using the shorter hashed key than to find it using the original value. The search can be stopped as soon as the minimum Levenshtein distance between prefixes of the strings exceeds the maximum allowed distance. 5 ) is smaller than the current length ( suppose 7 ), then the string will contain only the first 5 characters. str − The contents of this string are modified and broken into smaller strings (tokens). The missing component of the KMP algorithm is a computation of this overlap function: we need to know overlap(P[0. Imagine using this function in place of strcmp in the above example, all of the first and last combinations would output 0.
