Decodificar números convirtiéndolos en su letra correspondiente.
Number-to-letter decoding is the reverse of letter-to-number encoding. Given a sequence of numbers, convert each to the letter at that position in the alphabet: 1=A, 2=B, 3=C, etc. The key skill is quickly recognizing position values, especially for letters later in the alphabet.
1=A, 2=B, 3=C, ... 26=Z
- 19-21-14 = SUN
- 2-15-15-11 = BOOK
- 23-1-20-5-18 = WATER
Cómo reconocerlo
- Given numbers, asked to find the word
- Numbers are between 1 and 26
- Decode by finding the letter at each position
Errores comunes
- Confusing high numbers (is 20 T or U?)
- Not recognizing common patterns (15=O, 5=E)
- Mixing up single and double digit parsing
