# ch-1.pl Perl Weekly Challenge Task 1 Separate Digits 
#=============================================================================
# Copyright (c) 2023, Bob Lied
#=============================================================================
# You are given an array of positive integers.
# Write a script to separate the given array into single digits.
# Example 1 Input: @ints = (1, 34, 5, 6)
#           Output: (1, 3, 4, 5, 6)
# Example 2 Input: @ints = (1, 24, 51, 60)
#           Output: (1, 2, 4, 5, 1, 6, 0)
