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 J programming language

Source code in the j programming language

   s=: 'Hello,How,Are,You,Today'
   ] t=: <;._1 ',',s
+-----+---+---+---+-----+
|Hello|How|Are|You|Today|
+-----+---+---+---+-----+
   ; t,&.>'.'
Hello.How.Are.You.Today.

  '.' (I.','=s)}s  NB. two steps combined
Hello.How.Are.You.Today


   require 'strings'
   ',' splitstring s
+-----+---+---+---+-----+
|Hello|How|Are|You|Today|
+-----+---+---+---+-----+

   '.' joinstring ',' splitstring s
Hello.How.Are.You.Today


   '"'([ ,~ ,) '","' joinstring ',' splitstring s
"Hello","How","Are","You","Today"


   rplc&',.' s
Hello.How.Are.You.Today


   fn;._2 string,','


   fn ((;._2)(@(,&','))) string
