In combinatorial mathematics, a de Bruijn sequence of order n on a size- k alphabet A is a cyclic sequence in which every possible length- n string on A occurs exactly once as a substring (i.e., as a contiguous subsequence ). Such a sequence is denoted by B(k, n) and has length kn, which is also the number of distinct strings of length n on A.
A longest common subsequence ( LCS) is the longest subsequence common to all sequences in a set of sequences (often just two sequences). It differs from the longest common substring: unlike substrings, subsequences are not required to occupy consecutive positions within the original sequences. The problem of computing longest common ...
The set ret can be saved efficiently by just storing the index i, which is the last character of the longest common substring (of size z) instead of S[i-z+1..i]. Thus all the longest common substrings would be, for each i in ret, S[(ret[i]-z)..(ret[i])] . The following tricks can be used to reduce the memory usage of an implementation:

11. Athanasiou. “Immortal” is what this Greek last name means. 12. Gialamas. You’ll be shocked to know that this name means “sea.”. 13. Tsolakidis. “Son of Tsolak” is the meaning of ...
Knuth–Morris–Pratt algorithm. In computer science, the Knuth–Morris–Pratt algorithm (or KMP algorithm) is a string-searching algorithm that searches for occurrences of a "word" W within a main "text string" S by employing the observation that when a mismatch occurs, the word itself embodies sufficient information to determine where the ...
