You are encouraged to solve this task according to the task description, using any language you may know.
Separate the string "Hello,How,Are,You,Today" by commas into an array so that each index of the array 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.
Perl
Interpreter: Perl any 5.X
As a one liner without a trailing period, and most efficient way of doing it as you don't have to define an array.
print join('.', split(/,/, "Hello,How,Are,You,Today"));
If you needed to keep an array for later use, again no trailing period
my @words = split(/,/, "Hello,How,Are,You,Today"); print join('.', @words);
If you really want a trailing period, here is an example
my @words = split(/,/, "Hello,How,Are,You,Today"); print $_.'.' for (@words);
Ruby
string = "Hello,How,Are,You,Today".split(',') string.each do |w| print "#{w}." end

Generating a list form a string by splitting on a comma:

Joining the elements of a list by a period:
join list .
Thus the whole thing would look like this:
puts [join [split "Hello,How,Are,You,Today" ,] .]
If you'd like to retain the list in a variable with the name "words", it would only be marginally more complex:
puts [join [set words [split "Hello,How,Are,You,Today" ,]] .]
