// Operators in Groovy
/*
** Groovy provides us with 5 Common Types of Operators. These are:-
** 		1. Arithmetic Operators -> +,-,*,/,%,++,--
**		2. Relational Operators -> ==, =>, <=, !=, >, <
** 		3. Logical Operators -> &&, ||, |
** 		4. BitWise Operators -> &, |, ^, ~
** 		5. Assignment Operators -> +=, -=, *=, /=,%=
