CRYPTO2 - The Bytelandian Cryptographer (Act II)

no tags 

Encouraged by his last successful exploit, the Bytelandian fanatic cryptographer impudently encrypted a three-digit number by subtracting 1 from it.

This time he has really overstepped the mark! Soldier, go and beat him, for Burger King & Country! Oh, and remember your good manners, use Brainf**k (no other language is allowed).


An encrypted 3-digit positive integer.


The decrypted value.

Only special cases are when
1) Last digit is 9
2) Middle digit is 9

Handling 3 digit inputs with 3 digit outputs is sufficient.

999 is not a valid input.

Values are given in a '000' to '999'
Outputs must be from '001 to '1000'
Do not get rid of zeroes at the start of forget about 1000

Has there been any rejudge recently? I see that my solution that was accepted (about 2 years back) is marked "Wrong Answer" now...

I suppose the cell size is bigger than byte.

Too easy :P

1000 is not a 3 digit number, so no "999". If the input could be "99" my code would fail, but I got AC :P

Supporting "000".."998" will satisfy.

is 999 considered as input? and can I give input like 073? (starts with 0).
If yes, how should be the output for these inputs.. should they look like 074 or 74?

I think, this problem should be in challenge (shorter code, more points).
