#
# 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"

#
# This is a classic one-liner problem: join the words into a single string,
# then split this string into an array of strings at the separator, then
# only keep the non-empty strings by grepping for strings that contain one
# character.
