8. 18 marks. Consider the Scheme function all-within which consumes a list of numbers and two non-negative numbers base and rarge, and produces the list of just those values that are between (base-range) and (base+range), inclusive. For example, fall-within (cons 4 (cons 10 (cons - (cors 5 (coris & (cens 1 epsy)))))) 5 3) produces (cons 4 (cons 5 (cors 8 erpcy))). a) 16 marks] Complete the definition (the header and body) of all-within b) [2 marksUse check expect to write one test for all-witrin. Do not use the given example.

5. 110 marks] Consider the card structure definition. (define-struct card (value suit)) ii Acara is a structure (make-card v s), where ji v is an integer in the range from 1 to 10 and iis is a symbo. for suit, from the set 'hearts, ii 'diamonds, 'spades, and 'clubs. a) [2 marks] Define a constant called four-of-hearts corresponding to the card with suit 'hearts and value 4. Consider the Scheme function merge-cards which consumes two card structures (cl and c2) and produces a new card, according to the following rules: . If the suits of the two cards are the same, the new card has that suit and its value is the sum of the values of cl and c2, up to a maximum value of 10 • Otherwise, the new card has the value of cl and the suit of c2. b) 12 marks Write the contract of merce-cards (the function header is given below). c) 12 marks Write a single example for merge-cards. d) 16 marks Complete the body of the function merge-cards. (define (mergo-cards c! 02)

36. (2 points) Write a method that takes three integer parameters, startX, y, boxSize, and draws a row of adjacent squares, boxSize pixels on each side, with the upper left corner of the first square at startX, y. The row should extend all the way to the right edge of the display. The method needs to work for any values of the parameters. As an example the image to the right is the result of this sketch, assuming the sketch also includes your method definition. For different values, the last square could extend off of the display but there should be no space between the last square and the right edge. void setup() { partialRow (30, 50, 10);
