Decode the uppercase string using a Caesar shift of +5 (i.e., shift every letter 5 positions forward in the alphabet, wrapping around), then report the resulting 6-letter word in lowercase. Given: ELBJSR

Introduction / Context:
Caesar shifts are among the simplest substitution ciphers. A shift of +5 means A→F, B→G, …, V→A, W→B, X→C, Y→D, Z→E. After decoding, we output the result in lowercase.

Given Data / Assumptions:

• Cipher: Caesar +5 (forward by 5).
• Input: ELBJSR (uppercase).
• Output: 6 letters in lowercase.

Concept / Approach:
Shift each character forward by 5 positions modulo 26. Preserve order. Convert to lowercase at the end.

Step-by-Step Solution:

Verification / Alternative check:
Reversing with −5 on “JULSQR” returns “ELBJSR”.

Why Other Options Are Wrong:

• amwrnd, cxtndo, vithaw: Each corresponds to a different net shift or mis-ordered mapping and does not reverse to ELBJSR with −5.

Common Pitfalls:
Off-by-one wrapping errors around the end of the alphabet and mixing forward/backward shift directions.
