In past, people used this code to keep things secret. What they actually did was that the message was written in the immediate cipher text by converting each letter into a series of dots and dashes using the table. To convert the final enciphered text, they converted the 9 possible combinations(of 2 characters each) of the dash, space and dot characters into numbers 1-9 and the series of dots and dashes of the intermediate cipher text was converted to a series of numbers using it .During the World War 2, a soldier intercepted the code: 412214223112 and with the help from his country's intelligence bureau he got further information (which is not sufficient). The document he got from the intelligence says: "THE MESSAGE CONTAINS ONLY ONE SPACE ESSENTIALLY DIVIDING IT INTO TWO WORDS OF 6 AND 3 LETTERS, RESPECTIVELY. SOME PARTS OF THE FIRST WORD ARE "B__C" (FIRST LETTER IS B, THEN 4 LETTERS, AND THEN THE LAST IS C) AND THE LAST LETTER OF THE SECOND WORD IS "A". Help him decrypt the code!!!!!! Everyone please try this.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.
