Chapter 4 Discussion IV

  1. Target. tgt :: Integer -> [Integer] -> Integer. Given a target number and a list of numbers, find the smallest distance between the target number and any number in the list.

     tgt 5 [3,8,10,4]  == 1
     tgt 6 [10,4,30,50,9]  == 2
  2. Take in an ordered pair (x,y) and a list of floating point xs. Find out if the ordered pair is on the graph of y=x^3 corresponding to one of the xs. Return true if it is, false if not.

  3. Splash. Inputs: a list of ordered pairs and a point (one ordered pair). Output: All ordered pairs in the list within distance 10 of the point.
