I am tring to change the return type based on input basically, if input is true return string else return int.
Or maybe give example for : give example where we are accepting a arguement in macro and if its even calulate factorial of 5 and return it as integer and if the agruement is odd calculate the factoreial of 5 and return it as string. And name of both functions should be same. and logic of calculating 5! should not be repeated.
