Twin Prime Numbers
The Twin Prime numbers are the two Prime numbers having a difference of 2 between both of them. A prime having a prime gap of two is referred to as a twin prime. The twin prime term is used for a pair of twin primes. The twin primes are also known as prime pair or prime twin.
The pair (2, 3) is generally not considered as a pair of twin prime because 2 is the only even prime, and the pair is the only pair of prime numbers that differ from one.
Let's take some examples of Twin Prime numbers.
These are some of the twin prime pairs:
Note: Each and every pair of twin prime except (3, 5) is of the form (6n - 1, 6n + 1) for natural number.
Steps to check twin prime numbers
In order to check whether the numbers are twin prime or not, we have to follow the following steps:
Let's implement the code to check whether the numbers are twin prime numbers or not.
