Worksheet DrRacket 4. Define a procedure is-list? that takes one input and outputs true if the input is a List, 5. Define a procedure list-max that takes a List of non-negative numbers as its input and false Your procedure should behave identically to the built-in list? procedure, but you should not use list? in your definition. and produces as its result the value of the greatest element in the List (or 0 if there are no elements in the input List). For example, (list-max (ist 1 1 2 0) should evaluate to 2 6. Given the following code, state the results that the function evaluates into. map (lambda (s n) (substring s 1 n)) (list "pressing" "funny" "homework") (list 5 34) Note: (substring s ij)extracts the substring starting at position i up to j, position starts at zero.
