## Can Turing machine accepts palindrome?

## Can Turing machine accepts palindrome?

For an even-length palindrome a TM is defined after the machine runs and erases the first and last element without encountering a mismatch. Later on the turing machine accepts the string and the string is even-length palindrome.

**Can palindrome be odd?**

Explanation: String formed by characters at odd indices: bzb, which is a Palindrome. String formed by characters at even indices: aza, which is a Palindrome. Hence, the given string is an Even-Odd Palindrome.

### Which machine can read and accept palindromes over 0 1?

Turing Machine

Turing Machine Σ = {a, b} Γ = {a, b, B}

**What is palindrome in TOC?**

A palindrome is a string that reads the same forward and backward. Ex: otto, madamimadam, 0110, 11011, ǫ Lpal is not a regular language (can be proved by using the pumping lemma) We consider Σ = {0,1}.

## What spelled backwards is the same word?

A word, phrase or sentence that is the same both backwards and forwards is called a palindrome.

**Do palindromes have to be odd in length?**

If it is a palindrome then it must of odd length.

### Can palindromes be even length?

Nth Even length Palindrome Number 11,22,33,44,55,66,77,88,99,1001, etc. are some examples of even length palindrome numbers.

**What is even palindrome number?**

Nth Even length Palindrome Number 11,22,33,44,55,66,77,88,99,1001, etc. are some examples of even length palindrome numbers. We can also define it as first-half digits should be equal to second-half digits.

## What is one word that is an example of a palindrome?

Some examples of palindromic words are redivider, deified, civic, radar, level, rotor, kayak, reviver, racecar, madam, and refer. There are also word-unit palindromes in which the unit of reversal is the word (“Is it crazy how saying sentences backwards creates backwards sentences saying how crazy it is?”).

**Which one of the following machine can check for even length palindrome?**

A string w is called palindrome if reading w from left to right gives the same result as reading w from right to left.An even palindrome has even number of symbols.

### Can a DFA recognize a odd palindrome string?

9. Can a DFA recognize a palindrome number? Explanation: Language to accept a palindrome number or string will be non-regular and thus, its DFA cannot be obtained.

**How is PDA used for palindromes?**

Approach used in this PDA – For construction of even length palindrome, user has to use Non Deterministic Pushdown Automata (NPDA). A NPDA is basically an NFA with a stack added to it. The NPDA for this language is identical to the previous one except for epsilon transition.

## How many 4 digit odd palindromes are there?

For a palindromic number to be four digits, its last (and first) digit cannot be 0. So there are 4 possible first&last digits and 10 possible middle digits. There are 40 even 4-digit palindromes.

**How Never odd or even is palindrome?**

Never Odd Or Even is a palindromic phrase which reads the same way in both directions. It practically spelled itself out for me magically, letter by letter, in a moment of inspiration, but I thought that surely someone must have already thought of it. When I looked it up in a list of palindromes, I found that they had.
