Chapter 78 The Code on the Lieutenant

It happened in the 20s.

A cruiser "Magdeburg" of country Q hit a rock in the Baltic Sea and sank. Country G immediately dispatched ships to search after receiving the information.From this sunken ship, divers from country G salvaged the bodies of many victims, and one of them could be identified as a lieutenant from the military uniform.On the chest of the corpse was a lead box containing top-secret documents.

Open the lead box and find 3 cipher books - one is the strategic cipher used by the navy of country Q; the other is the tactical cipher used by the navy of country Q; the other is the commercial cipher of country Q.This discovery makes G country ecstatic.Therefore, he immediately organized a cryptanalysis organization directly under the Navy Headquarters, code-named "04 Post Office", chaired by Rear Admiral Reginald Hall, director of the G Naval Intelligence Bureau.This cryptanalysis organization has gathered dozens of authoritative linguists, mathematicians and computer technology experts.After several months of intense work, most of the codes were finally deciphered.

Relying on these three codebooks, country G has continuously intercepted a lot of valuable information, including the battle order and firepower distribution of country Q's fleets in various oceans, and the activities of country Q's spies dispatched around the world.As for all of this, Country Q has been kept in the dark, and they continue to use these codes.

The following is a set of passwords intercepted by country G: "101100102210001112".This is a piece of information sent to the country's intelligence headquarters by the spies stationed in country E by country Q.The content of this information is one of the following three: "Hope to return", "Send money", "Buy books".What is particularly interesting is that this set of passwords uses the rules of Chinese Pinyin, and this set of passwords uses the ternary system.

I would like to ask: What does this set of passwords mean?And please explain why.

[Answer] The six groups of numbers converted into decimal numbers are 10, 9, 11, 18, 1, 14, and the corresponding English letters are J, I, K, U, A, N, which means "sending money".
