...ame bucket as 2000 % 10
1000 % 20 same bucket as 2000 % 20
....
in other words, it would lead to many collisions.
This is because the factorization of 1000 (23, 53) and the factorization of 2000 (24, 53) have so many common factors. Thus prime numbers are chosen, since they are unlikely to have a...
what is the difference between XSD and WSDL
... because it is very specific for Web Services. The above WSDL (or in other words XSD) is created for a class called Book.java and it has created a SOAP service.

In hindsight, it should have been called "no break" (or p...

...ble value. That is dubious - code that breaks when changing a user-visible word is considered "fragile". The second solution shown in Parrot's answer is fine - it is the same as this one. Parrot's second solution also shows the corresponding code to write, hence it is a more useful answer than this ...
