# ch-1.pl Perl Weekly Challenge 253 Task 1 Split Strings
#=============================================================================
# You are given an array of strings and a character separator.
# Write a script to return all words separated by the given character
# excluding empty string.
# Example 1 Input: @words = ("one.two.three","four.five","six") $separator = "."
# Output: "one","two","three","four","five","six"
# Example 2 Input: @words = ("$perl$$", "$$raku$") $separator = "$"
# Output: "perl","raku"
