About Coding and Decoding
Coding and decoding questions replace letters, numbers, words or symbols with another pattern and ask you to identify the rule or decode a new item. Methods include alphabet positions, shifts, reversals, substitution, rearrangement, numerical values and separate rules for different parts of a code.
