Decode the uppercase string using a Caesar shift of −6 (backward by 6). Output the result in lowercase. Given: LKFZOS

Introduction / Context:
We again use a uniform backward shift. The answer must be a 6-letter lowercase sequence.

Given Data / Assumptions:

• Cipher: Caesar −6.
• Input: LKFZOS.

Concept / Approach:
Compute each letter shifted by −6, wrapping around if needed.

Step-by-Step Solution:

Verification / Alternative check:
Applying +6 to “hijump” reproduces “lkfzos”.

Why Other Options Are Wrong:

• napkin, mzkbnx, mzkbxn: These correspond to different shift values or transpositions.

Common Pitfalls:
Sign mistakes (using +6 instead of −6) and wrap handling at a–z or A–Z boundaries.
