back to boardSome Hints... to solve this problem input1 : 05 26 2C 52 69 14 3F 31 4C 2A 69 65 1A 26 4B input2 : 61 07 28 41 3B 63 07 2C 52 22 21 69 72 0B 42 5E answer : 41 43 4D 20 49 43 50 43 20 4E 45 45 52 43 27 32 (P.S : I put the spaces only for that is easy to read && understand) Why is first 2 bytes in answer is 41...? Cuz, 61h xor 20h = 41h (20h -> 32d = ' ' = Space); How to find the second,third,...? 41h xor 05h = 44h 44h xor 07h = 43h(Second 2 bytes); 43h xor 26h = 65h 65h xor 28 = 4Dh (Third 2 bytes); Last some tips: if you use algos for convert from Dec to Hex be careful; your algo should convert 1 : 0d to 00h (not to 0h); 2 : 5d to 05h (not to 5h); GoodLuck!!! ;-) Edited by author 17.05.2009 08:41 Re: Some Hints... to solve this problem thnx! |
