Past challenges

May I just say thank you to all participants - without you this challenge would not have worked. I also thank you for your patience as it was my first challenge on mircscripts.org. A new challenge will be made in the next week or so. I invite you to join in this one also :) ... Now onto the challenge results...

There were 27 entries submitted, 19 valid and 8 invalid entries. Entries that contained subtle mistakes were corrected (aren't I nice?) and the new code size in bytes reflects this correction.

Congratulations to the winner myndzi and in joint second position visionz, Ag2X and poste9.

Winner:

Invalid Entries

blinks	212 bytes	* Failed on almost every test
addy	270 bytes	* Failed on --> 35,42,43,44,45,46,47,48,54,60,62,63,64,65,66,71,72,74,75,76,79,80,91,92,93,94 tests
impuLse	300 bytes	* /set: line too long (line 6, inctext-impuLse.mrc)
tontito	316 bytes	* Failed on --> 35,42,43,44,45,46,47,48,54,60,62,63,64,65,66,71,72,74,75,76,79,80,91,92,93,94 tests
FroggieDaFrog	376 bytes	* Uses regular expressions, against the rules
biggem001	378 bytes	* Failed on --> 48,58,61,67,68,69,78 tests
^Vampire^	553 bytes	* String too long: $bvar (line 5, inctext-vampire.mrc) - Was replacing ascii values which made the string size * 4-1 larger on upper case values and * 3-1 on lower case. Did not support 900 chrs.
RockeyRex	590 bytes	* Did not return the values as asked, strings with numbers was supose to report $null although this script incremented the numbers, along with the characters. This, although impressive as it worked flawlessly, was not asked for.

Description:

New challenges as of 2006 !


You are to create an alias that will accept a text string of A-Z and a-z characters and increment it and return the output. If the input value contains characters that are not in this range – it will return $null.

The alias must preserve upper and lower cases in their appropriate positions.

If left of string is ‘Z’ then ‘A’ will be appended to the beginning of the string.

If left of string is ‘z’ then ‘a’ will be appended to the beginning of the string.
(Preserving cases even when carrying)

Example:

$inctext(1) = $null
$inctext(1A6aajo46) = $null
$inctext(?) = $null
$inctext(a) = b
$inctext(z) = aa
$inctext(Z) = AA
$inctext(aB) = aC
$inctext(BB) = BC
$inctext(ABC) = ABD
$inctext(ABc) = ABd
$inctext(AbZ) = AcA
$inctext(ZZZ) = AAAA
$inctext(YzZ) = ZaA
$inctext(Zzz) = AAaa
$inctext(zZZ) = aaAA
$inctext(mZzzZZ) = nAaaAA
$inctext(CcC) = CcD
$inctext(ppZ) = pqA
$inctext(aZzZzZ) = bAaAaA
