TASK on Polymorphism

[YASWANTHKUMARJNTUACE]

/*Task :

• Create a Method that single can perform all mathematical operations like
  add, sub, mul, div
  Method(a,b,..) add, sub, mul
  you can pass parameter and operation type so that it will perform that operation on those parameters.
  Method(10,20, add) { }
