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

Introduction / Context:
Decoding continues with a backward shift of 6.

Given Data / Assumptions:

• Cipher: Caesar −6.
• Input: TZCLJW.

Concept / Approach:
Shift each character 6 places backward modulo 26.

Step-by-Step Solution:

Verification / Alternative check:
Re-encoding “fiecrg” with +6 returns “tzcljw”.

Why Other Options Are Wrong:

• algpkj, vbfnic, ymswtx: Different shift signatures; do not invert to TZCLJW under +6.

Common Pitfalls:
Arithmetic off-by-one at alphabet edges and mixing letter cases.

Final Answer:
fiecrg
