Table of Contents

Problem Statement

Separate the string "Hello,How,Are,You,Today" by commas into an array (or list) so that each element of it stores a different word. Display the words to the 'user', in the simplest manner possible, separated by a period. To simplify, you may display a trailing period.

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Tokenize a string step by step in the Common Lisp programming language

Source code in the common programming language

(defun comma-split (string)
  (loop for start = 0 then (1+ finish)
        for finish = (position #\, string :start start)
        collecting (subseq string start finish)
        until (null finish)))

(defun write-with-periods (strings)
  (format t "~{~A~^.~}" strings))
