Zahl-zu-Buchstabe-Codes

Lernen

Zahlen entschlüsseln, indem man sie in den entsprechenden Buchstaben umwandelt.

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

So erkennen Sie es

• Given numbers, asked to find the word
• Numbers are between 1 and 26
• Decode by finding the letter at each position

Häufige Fehler

• Confusing high numbers (is 20 T or U?)
• Not recognizing common patterns (15=O, 5=E)
• Mixing up single and double digit parsing
