Input (int, int) Output (int)
1, 25 5
26, 80 4
50, 300 13
19, 30 0
5, 15 2

class CountTwinPrimes

{    public static void main(String s[])
    {
        System.out.println("The number of the twin primes in the given range are : " + countTwinPrimes(5, 15));

    }


public static int countTwinPrimes(int rangeStart, int rangeEnd) {
//Write code here to count the number of the twin primes in the given range
}
}
