Write a program **to count the number of the twin primes** in the given input range. Twin primes are those whose difference is two and the both the numbers are primes. For Eg. 1-3, 3-5, 5-7, 11-13, 17-19 are twin primes where as 5-11 or 19-21 or 19-23 are not.

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

}

}
