Hi! I need a bit of help with both of these questions, please in SML

Problem 3: Functions and map Write a recursive function called sumlist that computes the sum of the numbers in a list. Write a recursive function called powerlist that computes the power of n (given as a parameter) of the numbers in a list. You will use map. For example, powerlist ([6,4,3],5)=[65,45,35]. Provide the SML code and screenshots. Show evidence of testing of your functions. Problem 4: BinaryTree datatype See the slides and code the BinaryTree datatype and its functions. Test each function exhaustively. In parallel, you will show how to define BinaryTree in Java. Integrate your answers in the table below
