<br/>--> above code filters the first 1000 primes to check if the difference between two prime numbers is '2' and displays the list of twin primes as (3 5), (5,7), (11,13) etc

--> above code filters the first 1000 primes to check if the difference between two prime numbers is '2' and displays the list of twin primes as (3 5), (5,7), (11,13) etc

This list is stored as a table named 'ps'. Using the below code statement, this table is further used to map it to the reciprocals of the twin primes and add them.
