Temple University Common Lisp Function Code Project

1.Write a Common Lisp function named myList which creates the following list
and returns it
(4 (7 22) “art” (“math” (8) 99) 100)
 

2.Write a Common Lisp function named leapYear which takes no required
parameters and returns an ordered list containing all leap years from 1800 though 2021.
The list of leapyears must be calculated, no points will be given for a hard-coded list.
 

3.Write a Common Lisp function named union- which takes two list
parameters. union- returns a single list which contains the separate unique entities
from both lists, with no duplication. You are not allowed to use the predefined union
function for this function.

4. [10 points] Write a Common Lisp function named avg with a single parameter named
aList. avg returns the average of all elements in aList. Assume all elements in aList are
numbers. If given an empty list, avg should return NIL. The avg function must be tail
recursive.
 

5. [15 points] Write a Common Lisp function named isType which takes a single
parameter named dataType. isType will return an anonymous function which takes a
single parameter and returns true if the parameters data type is the data type specified
in dataType. Otherwise the anonymous function returns false.
 

6. [15 points] Write a Common Lisp function named taxCalculator with three
parameters: limit, rate, and values. limit and rate will be numbers, values will be a list.
taxCalculator returns a list with the same elements and ordering of the values
parameter EXCEPT every element which is greater than limit is multiplied by rate.
Assume that all elements of the values list are numbers.  
BONUS: Make taxCalculator tail recursive +5 points
