Agent 17 Puzzle -

Ciphertext: Yvccf Shift backward by 17: H → A? Wait, let's do: Y (25th letter) - 17 = 8 = H. But that doesn't form a word. Actually, shift forward by 9: Y+9 = H? No – careful: The common trick is ROT-17 , which is identical to ROT-9 in reverse. Test a word: "HELLO" with ROT-17: H(8)+17=25=Y, E(5)+17=22=V, L(12)+17=29 mod26=3=C, L→C, O(15)+17=32 mod26=6=F → "YVCCF". So if you see "YVCCF", ROT-17 back to "HELLO".

Hint 1: Look at minutes: 00,15,45,15,45,00 — pattern 00→15→45 then repeats offset. Hint 2: The letters form a word. Ciphertext: Yvccf Shift backward by 17: H → A

Let’s systematically find all quadruples (a,b,c,d) with 0–9, product 72: Actually, shift forward by 9: Y+9 = H
