decode_the_morse_code.py

# The Morse code encodes every character as a sequence of "dots" and "dashes".
# For example, the letter A is coded as ·−, letter Q is coded as −−·−, and digit 1 is coded as ·−−−−.
# The Morse code is case-insensitive, traditionally capital letters are used.
# When the message is written in Morse code, a single space is used to separate the character codes
# and 3 spaces are used to separate words. For example, the message HEY JUDE
# in Morse code is ···· · −·−−   ·−−− ··− −·· ·.
# NOTE: Extra spaces before or after the code have no meaning and should be ignored.
# In addition to letters, digits and some punctuation, there are some special service codes,
# the most notorious of those is the international distress signal SOS (that was first issued by Titanic),
# that is coded as ···−−−···. These special codes are treated as single special characters,
# and usually are transmitted as separate words.
# Your task is to implement a function that would take the morse code as input
# and return a decoded human-readable string.
