Reverse Coding
Reverse Coding problems involve reversing the order of letters in a word (e.g., 'CAT' becomes 'TAC'). This is the simplest pattern-based coding. You must identify that the code is the original word written backwards and apply the same operation to new words.

Prerequisites
How to Solve Reverse Coding Problems
Step 1: Compare the given word and its coded version
Step 2: Check if the code is the reverse of the original word
Step 3: Verify that reversing the code gives back the original
Step 4: For the target word, write its letters in reverse order
Step 5: Ensure the reversal is exact (no other transformations)
Step 6: Present the reversed word as the answer
Example Problem
Example: If 'TABLE' is coded as 'ELBAT', how is 'CHAIR' coded? Solution: Step 1: TABLE → ELBAT (reverse order) Step 2: CHAIR reversed = RIAHC Answer: RIAHC
Pro Tips & Tricks
- To reverse a word, write it from last letter to first
- The length of the word remains the same
- Common reversed words: CAT→TAC, DOG→GOD, PEN→NEP
- Palindromes (MADAM, LEVEL) remain unchanged when reversed
- For multi-word phrases, reverse the entire string including spaces
- Check if the problem uses 'reverse' or 'write backwards' terminology
