Le lettere sono sostituite con simboli secondo una chiave data.
Symbol substitution codes replace letters with symbols (@, #, $, %, etc.) according to a provided key. Unlike alphabetic shifts, there's no predictable pattern—you must use the key exactly as given. The key may only cover some letters, with others following a different rule.
A=@, B=#, C=$, etc. (as specified in key)
- If A=@, B=#, C=$ then ABC = @#$
- If X=!, Y=?, Z=* then XYZ = !?*
- Decode #@$ using A=@, B=#, C=$ → BAC
Come riconoscerlo
- Message contains symbols not normally in words
- A key is provided mapping letters to symbols
- No predictable pattern—must use the key
Errori comuni
- Trying to find a pattern instead of using the key
- Confusing similar-looking symbols
- Misreading which symbol maps to which letter
Soluzione passo per passo
Decodifica '#@$' usando la chiave: A=@, B=#, C=$
- Cerca # nella chiave: B=#, quindi # = B
- Cerca @ nella chiave: A=@, quindi @ = A
- Cerca $ nella chiave: C=$, quindi $ = C
Risposta: BAC
