Master-Level Question 1: Recursive Function in Lisp
Let's dive into our first master-level question, which focuses on implementing a recursive function in Lisp to calculate factorial.
Question:
Write a recursive function in Lisp to calculate the factorial of a given number.
Solution:
(defun factorial
(if (<= n 1)
1
(* n (factorial (- n 1)))))
Explanation:
In Lisp, defining a recursive function involves using the defun keyword followed by the function name and its parameters. The factorial function here checks if the number n is less than or equal to 1. If true, it returns 1 (base case). Otherwise, it multiplies n with the factorial of n-1.
Master-Level Question 2: List Manipulation in Lisp
Our second master-level question involves manipulating lists in Lisp.
Question:
Define a function in Lisp that takes a list of integers as input and returns a new list containing only the even numbers from the original list.
Solution:
(defun filter-even (lst)
(cond ((null lst) nil)
((evenp (car lst)) (cons (car lst) (filter-even (cdr lst))))
(t (filter-even (cdr lst)))))
(defun even-numbers (lst)
(filter-even lst))
Explanation:
The filter-even function uses recursion (filter-even (cdr lst)) to iterate through the list (lst). If the first element ((car lst)) is even (evenp (car lst)), it adds it to the result list using cons. Otherwise, it continues to the next element until the list is exhausted (null lst).
