In metaprogramming we'll sometimes define a method at runtime, and therefore won't know its name beforehand. Your task is to write a method that takes two arguments: an object, and a method name.
The given method name will always be a symbol, and the receiving object will always know how to respond to the given method. The given method will never require any arguments.
Your method should return the result of calling method on obj.
For example, the following method call...
dynamic_caller('zaphod!', :upcase)
... should return ZAPHOD!
def dynamic_caller(obj, method)
obj.send(method)
end
