Las letras se reemplazan por símbolos según una clave dada.
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
Cómo reconocerlo
- Message contains symbols not normally in words
- A key is provided mapping letters to symbols
- No predictable pattern—must use the key
Errores comunes
- Trying to find a pattern instead of using the key
- Confusing similar-looking symbols
- Misreading which symbol maps to which letter
Resolución paso a paso
Decodifica '#@$' usando la clave: A=@, B=#, C=$
- Busca # en la clave: B=#, así que # = B
- Busca @ en la clave: A=@, así que @ = A
- Busca $ en la clave: C=$, así que $ = C
Respuesta: BAC
