Use a quick script logic mentally: If a (0) → f (5) for first letter of first word? No, a to f is +5, but then f to d is –2 (inconsistent). So not a single Caesar shift for whole message — unless the key changes per word, but that's unlikely.
Reverse string order: "shwayy fydyw drdsht brnamj afdl" — no. Assume it's English. Frequency: Letters in text: a(2), b(1), d(4), f(2), h(2), j(1), m(1), n(1), r(2), s(1), t(1), w(2), y(4). afdl brnamj drdsht fydyw shwayy
afdl = "from": f→a: shift –5 (or +21) r→f: shift –12 o→d: shift –11 m→l: shift –1 — inconsistent. Use a quick script logic mentally: If a
Try afdl = "with": w→a: +4? No, w=22, a=0: difference +4 mod 26? 22+4=26=0 yes. i→f: i=8, f=5: –3 mod 26 — not same shift. So not Vigenère with fixed key length 1. Reverse each word: afdl → lfda brnamj → jmanrb drdsht → thsdrd fydyw → wydyf shwayy → yyawhs Result: not English. Reverse string order: "shwayy fydyw drdsht brnamj afdl"
