Morse code, which was initially employed via telegraph lines, comprises a series of dots and dashes.
These symbols can also be conveyed through flashing lights or electrical pulses, particularly in the realm of amateur radio.
In this system, dots signify a brief signal, while dashes indicate a more extended signal.
Every letter in the English alphabet (A-Z), digits from 0 to 9, and various punctuation marks (such as the fraction bar or slash "/") are represented by unique combinations of these dots and dashes.
