input: Write a python function to create an instance of the Employee class and return its attributes as a dictionary.
  assert create_employee("Alice", 30, 70000) == {'name': 'Alice', 'age': 30, 'salary': 70000}
  assert create_employee("Bob", 25, 50000) == {'name': 'Bob', 'age': 25, 'salary': 50000}
  assert create_employee("Charlie", 40, 100000) == {'name': 'Charlie', 'age': 40, 'salary': 100000}
output: def create_employee(name, age, salary):
      class Employee:
          def __init__(self, name, age, salary):
              self.name = name
              self.age = age
              self.salary = salary
  
      employee = Employee(name, age, salary)
      return {'name': employee.name, 'age': employee.age, 'salary': employee.salary}
