Twin Prime Numbers between 1 and n | Python program to illustrate ... To print total number of twin prime using Sieve of Eratosthenes.
Create a boolean array " prime [ 0 . . n ] " and initialize all entries it as true . A value in prime [ i ] will finally be false if i is Not a prime , else true ..
If prime [ p ] is not changed , then it is a prime.
Update all multiples of p.
check twin prime numbers display the twin prime numbers.
