The following two questions use the following enum definition. enum Two { case first(A) case second(B)}(4 pts) Write an implementation of the following function which will compile and run, or say if it's impossible to implement. If it's impossible to implement, explain why. func impl4(t1: Two, t2: Two) -> Two { ... }(5 pts) Write an implementation of the following function which will compile and run, or say if it's impossible to implement. If it's impossible to implement, explain why. func impl5(a: A, b: B) -> Two { ... }

Write a program that uses a widgetviewer object to do the following: generate two random integers between 1 and 9 (inclusive). name one of them x, the other y. display them to the user using jlabel objects. create a jlabel object displaying the text "enter an operation number." create a jtextfield for the user's input. create a jbutton displaying the text "press here when you've entered your operation." use addandwait to add it to the widgetviewer object. when the user clicks the jbutton, evaluate operation in the following order to determine the one and only mathematical operation to perform on x and y. use a jlabel to display the result. if operation is between 1 and 10 inclusive, add x and y. if operation is evenly divisible by 4, subtract y from x. if operation is evenly divisible by 5, use integer division to divide y into x. if operation is an even number, use floating point division to divide y into x. if none of the other tests on operation apply, multiply x and y. note: operation can be negative or zero.
