Problem: Write a Java program to check whether the given number is Twisted Prime or not.

A number is said to be Twisted Prime if it is a prime number and its reverse is also a prime number.

Example:

Steps to check Twisted Prime in Java:

1. Input a number.
2. Check if the number is prime.
3. If the number is prime, compute its reverse.
4. Check if the reverse is prime.
5. If both step-2 and step-4 are true, then the input number is Twisted Prime, else not.

Here is the implementation of the steps in Java:

Output:

Enter a number: 31
Twisted Prime

In the above program, the `isPrime(int n)` function returns `true` if the passed number (i.e. `n`) is a prime number, otherwise it returns `false`.

We use the `isPrime(int n)` to check whether the input and its reverse are prime or not.

If anyone of them is not a prime number then it means input is not a Twisted Prime.

If both the numbers are prime then the input is said to be a Twisted Prime number.

In this programming example, we learned to check Twisted Prime number in Java programming language.
