Build an FA that accepts the language of all strings of length 4 or more such that the next-to-last letter is equal to the second letter of the input string?
Alright, buckle up, buttercup. To build that finite automaton, you'll need states representing the possible conditions of the next-to-last letter matching the second letter. Start with an initial state, transition based on the second letter, and end in an accepting state if the next-to-last letter matches. Just remember, the next-to-last letter needs to be the same as the second letter for the FA to accept that sassy string.

What is the difference between Oracle data types char and varchar2?
Character string values storage:1. CHAR:§ Stores strings of fixed length.§ The length parameter s specifies the length of the strings.§ If the string has smaller length it padded with space at the end§ It will waste of a lot of disk space.§ If the string has bigger length it truncated to the scale number of the string.2. VARCHAR:§ Stores strings of variable length.§ The length parameter specifies the maximum length of the strings§ It stores up to 2000 bytes of characters§ It will occupy space for NULL values§ The total length for strings is defined when database was created.3. VARCHAR(2):§ Stores strings of variable length.§ The length parameter specifies the maximum length of the strings§ It stores up to 4000 bytes of characters§ It will not occupy space for NULL values§ The total length of strings is defined when strings are given

How many strings can be formed of length 4 from a language containing 10 letters?
In a "language" containing just 10 letters, there are 10,000 four-letter permutations. It's easy to work out if you simply replace the letters with decimal digits 0-9. The first permutation is 0000, followed by 0001, 0002, 0003, ..., 9997, 9998 and 9999.
How do you build a PDA that accepts the language even palindrome?
The PDA accepting the even length palindrome is: Let us suppose the string of (0,1) as even length palindrome. Let us consider the string be wwr -- the moves of PDA then can be defined as: d(q0,E,E)= (qo, E) d(q0,0,z0)= (q0,0,z0) d(q0,1,z0)= (q0,1z0)
How would you write a function prototype for a function named calcAreaReact that accepts two arguments width and length and returns the area.?
double calcAreaRect (double a, double b);
How many strings of length less than 4 contains the language described by the regular expression (x y)y(a ab)?
To find the number of strings of length less than 4 that match the regular expression ((x y)y(a , | , ab)), we first analyze the components. The expression can generate strings of length 3: "xyy", "xyab", and also strings of length 2: "xyy" (from the first part) and "xy" (if we consider the empty string for the last part). Therefore, the valid strings of length less than 4 are "xyy", "xyab", and the empty string, leading to a total of 3 valid strings.
What is an example of a decidable language?
An example of a decidable language is the set of all even-length strings. This means that a Turing machine can determine whether a given string has an even number of characters in it.
How many bit strings are there of length eight?
Every bit can either be a 0 or 1. So to find the amount of bit strings of length either, you do 2length to find the amount of bit strings there are of a given length.
How can the Pumping Lemma be applied to demonstrate that a language is not regular?
The Pumping Lemma is a tool used in theoretical computer science to prove that a language is not regular. It works by showing that for any regular language, there exists a "pumping length" such that any string longer than that length can be divided into parts that can be repeated to create new strings not in the original language. If this property cannot be demonstrated for a given language, then the language is not regular.

How many strings are there of lower case letters of length 4 or less?
By the sum rule we can count the number of strings of length 4 or less by counting the number of strings of length i, for 0 <= i <= 4, and then adding the results. Now there are 26 letters to choose from, and a string of length i is specified by choosing its characters, one after another. Therefore, by the product rule there are 26^i strings of length i. The answer to the question is thus: sum i=0 to 4 ( 26^i = 1 + 26 + 676 + 17576 + 456976) = 475,255.
How many strings of length 0 that start with 1 bit or end with 2 bits are possible?
There are no zero-length strings that start with 1 bit or end with 2 bits. In a zero-length string, there are no bits at all.

How long are harp strings?
The length of harp strings can vary depending on the type of harp. For example, concert grand pedal harp strings can be around 6 feet long, while smaller lever harp strings may be around 3 feet long. The length of the strings corresponds to the pitch they produce when plucked.
