Provide a regular expression that describes all bit-strings that length is at least one and at most three.
Solution :
Bit string means a string which contains number of bits either 0 or 1.
So the RE is ((0+1)+(0+1)(0+1))+(0+1)(0+1)+(0+1)
From first part we can get length 1 strings from second part we can get the strings of length two and from third part we can get the strings of length 3.Here + means take any one of them.

****** Theory of Computing ********* 1. Provide a regular expression for “all even length strings of b’s”. 2. List all words of length 4 in Language((a+b)* a). Also, provide an English description of this language.
1. Use a Regular Expression to define the set of all bit strings of one or more 0's followed by only a 1. 2. Use a Regular Expression to define the set of all bit string of two or more symbols followed by three or more 0's. 3. Are these two grammars the same? a. S-> aSb|ab|λ b. S-> aAb|ab A->aAb|λ 4. Use the process of elimination to find the language of the following FA: (see picture for diagram) 5....
Regular Expression of All strings of x y z with. At Most one x And At Most three y In the whole string
Provide a regular expression for the following languages: (a) the set of all strings over {a, b} that start with ab and end with ba, (b) the set of strings over {a, b} where four consecutive occurrences of both letters occur in every word.
Find all strings with length exactly 4 represented by the regular expression, a*bb*. Put your answers in alphabetical order separated by a single space and no commas.
Write a regular expression that captures the set of strings composed of 'a', 'b', and 'c', where any string uses at most two of the three letters (for example, "abbab" is a valid string, or "bccbb", or "ccacaa", but not "abccba": strings that contain only one of the three letters are also fine). Give a non-deterministic finite automaton that captures the regular expression from Using the construction described in class, give a deterministic version of the automaton. Repeat the previous...
Let A be the set of all bit strings of length 10. 1. How many bit strings of length 10 are there? How many bit strings of length 10 begin with 1101? How many bit strings of length 10 have exactly six 0's? How many bit strings of length 10 have equal numbers of O's and 1's? How many bit strings of length 10 have more O's than 1's? a. b. c. d. e.
Construct a regular expression that recognizes the following language of strings over the alphabet {0 1}: The language consisting of the set of all bit strings that start with 00 or end with 101 (or both). Syntax The union is expressed as R|R, star as R*, plus as R+, concatenation as RR. Epsilon is not supported but you can write R? for the regex (R|epsilon).
Write down the regular expressions for the following set of strings over {a, b}: 1.Strings that contain no more than one occurrence of the string aa. 2.All strings containing aba: 3.All strings of odd length 4.A string in this language must have at least two a's. 5.All strings that begin with a, and have an even number of b Bonus - All strings with “a” at every odd position
Run JFlap, and use File->Open to open the problem1.jff file that we have given you. In problem1.jff, build a deterministic finite-state machine that accepts all bit strings containing at least three 1s and at most one 0, and that rejects all other bit strings. This problem requires at least nine states. You may use more states if necessary (there’s no penalty for doing so), but if you have time, try to get as close to the minimum as possible! Here...
