Decode the uppercase string using a Caesar shift of −6; output in lowercase. Given: GOYEPS

Introduction / Context:We continue with the −6 Caesar scheme. Apply it to each letter in order, wrap around Z→T, etc.

Given Data / Assumptions:

• Cipher: Caesar −6.
• Input: GOYEPS.

Concept / Approach:Compute L−6 modulo 26 for each L.

Step-by-Step Solution:

Verification / Alternative check:+6 on “vbfnic” reconstructs “goyeps”.

Why Other Options Are Wrong:

• algpkj, ymswtx, abuklm: Different shift choices; they do not invert to GOYEPS with +6.

Common Pitfalls:Reversing shift direction or missing wrap-around.

Final Answer:vbfnic
