Mirror Code
Mirror Code problems involve replacing each letter with its mirror image in the alphabet, where A↔Z, B↔Y, C↔X, and so on. This is also known as the Atbash cipher. These problems test your understanding of symmetrical relationships in the alphabet.

Prerequisites
How to Solve Mirror Code Problems
Step 1: Identify each letter in the given word or code
Step 2: Find the mirror pair for each letter using the rule: mirror position = 27 - original position
Step 3: Convert the mirror position back to a letter
Step 4: Write the mirror letters in the same order as the original
Step 5: For decoding, apply the same mirror rule (it is its own inverse)
Step 6: Verify that the mirror operation is correct for all letters
Step 7: Present the final coded or decoded word
Example Problem
Example 1: Code the word 'CAT' using mirror coding (A↔Z, B↔Y, ...). Solution: Step 1: C (3), A (1), T (20) Step 2: Mirror positions: C: 27-3=24 → X, A: 27-1=26 → Z, T: 27-20=7 → G Step 3: Coded word = XZG Answer: XZG Example 2: Decode 'XZG' using mirror code. Solution: Step 1: X (24), Z (26), G (7) Step 2: Mirror: X: 27-24=3 → C, Z: 27-26=1 → A, G: 27-7=20 → T Step 3: Decoded word = CAT Answer: CAT
Pro Tips & Tricks
- Memorize mirror pairs: A↔Z, B↔Y, C↔X, D↔W, E↔V, F↔U, G↔T, H↔S, I↔R, J↔Q, K↔P, L↔O, M↔N
- The sum of mirror pair positions is always 27
- Middle pairs: M(13) ↔ N(14) sum to 27
- Mirror coding is its own inverse (self-reciprocal)
- For quick coding, use the pattern: first becomes last, second becomes second-last
- Vowels map to vowels? A(1)→Z(26), E(5)→V(22), I(9)→R(18), O(15)→L(12), U(21)→F(6) - not vowels
