Coded Directions
Coded Directions problems use symbols, letters, or numbers to represent cardinal and intercardinal directions. You must decode the code, apply turns or movements, and encode the result. These problems test your ability to work with abstract representations of directions.

Introduction to Coded Directions
Coded Directions problems use symbols, letters, or numbers to represent cardinal and intercardinal directions. You must decode the code, apply turns or movements, and encode the result. These problems test your ability to work with abstract representations of directions.
Prerequisites
How to Solve Coded Directions Problems
Step 1: Identify the coding scheme (e.g., A=North, B=South, C=East, D=West)
Step 2: Decode the given coded direction to its actual direction
Step 3: Apply any turns or movements to get the new actual direction
Step 4: Encode the new direction back using the same coding scheme
Step 5: For multiple operations, apply sequentially or calculate net effect
Step 6: Verify that the code mapping is consistent throughout
Step 7: Present the answer in coded form
Example Problem
Example: If A=North, B=South, C=East, D=West, what is the code for the direction you face after turning right from A? Solution: Step 1: A = North Step 2: Turn right from North = East Step 3: East is coded as C Answer: C
Pro Tips & Tricks
- Always create a bidirectional mapping between codes and directions
- Decode first, perform operations, then encode the result
- For turn sequences, use net rotation method to find final direction
- Common coding schemes: A,B,C,D for N,S,E,W; 1,2,3,4; @,#,$,%; P,Q,R,S
- Test the coding scheme with a sample direction to verify mapping
- If codes are for intercardinal directions, ensure all 8 directions are mapped
