What is the Morse code for distress signal SOS?

Explanation:
In Morse code, distress signals are chosen for immediate recognizability, using a simple, memorable pattern. SOS is three short signals, followed by three long signals, then three short signals. Since S is three dots and O is three dashes, putting them together gives ...---... when transmitted as a continuous sequence, which helps it stand out in noisy conditions. Other sequences shown map to different letters or signs (for example, a colon or other prosigns), so they don’t represent the distress call. The three-short, three-long, three-short pattern is the universally recognized SOS distress signal.
