complement of the epsilon regex which is any letter, one or more times. I.e. the complement regex must match all strings which are prefixes of the regular regex, but have incompatible suffixes: d followed by junk. The mismatches through the (abc) part of *(abc) are reflected in the branches aa[acd][abcd]* and aab[abd][abcd]*. I.e. the
The language produced by r contains all words, x, such that for all instances of substring a b b in x, this substring is followed by at least one b. The complement of this language contains all words, y, that have at least one occurrence of a b b as a substring and it is not followed by b.

Elasticsearch supports regular expressions in the following queries: Complement of DFA Intersection of Regular Languages Contents Complement Let M = < Q , , q 0, , A > be a DFA that accepts a language L. Then a DFA that accepts the complement of L, i.e. * - L, can be obtained by swapping its accepting states with its non-accepting states, that is M c = < Q , , q 0, , Q - A > is a DFA that accepts * - L . Complement : If L (G) is regular language, its complement L’ (G) will also be regular. Complement of a language can be found by subtracting strings which are in L (G) from all possible strings. Write a function called reverse_complement () that takes a DNA sequence parameter and returns its reverse complement (i.e., reverses the string, switches A’s and T’s, and switches G’s and C’s).
