In 25—27, find a regular expression that defines the given language.

26. The language consisting of strings of a’s and b’s in which the third character from the end is a b.

To determine

Find a regular expression that defines the given language.

The language consisting of all strings of a's and b's in which the third character from the end is ab.

Explanation

Given information:

It is required to write a regular expression that defines the language consisting of all strings of a's and b's in which the third character from the end is ab.

Concept used:

Here (a|b)* represents any string at all made up of a's and b's this part is followed by ab which is followed by any one of the expression aa,ab,ba or bb.

Calculation:

It is required to write a regular expression that defines the language consisting of all strings of a's and b's in which the third character from the end is ab. The possible solution for the statement is (a|b)*b(aa|ab|ba|bb)
