[ENDED] Code Golf Contest #8
« on: September 01, 2014, 11:56:35 am »
This challenge should confuse some people.

NEXT: Here
PREVIOUS: Here

Challenge 8

Problem

Check if a string is conveniently palindromic, and output 1 if it is and 0 if it isn't. This means that the char pairs () {} [] <> should be handled such that strings such as
Code: [Select]
(<)i(>)
<}<{}>{>
][()][
}{[]}{would return 1, and strings like
Code: [Select]
())(
<(){}[][}{)(<
(({))
<<would return 0.
Case insensitive when possible.

Deadline
September 8, 2014, 1:00 AM EST

If any further clarification is needed, contact me. I'll try not to get everything backwards for you. (*crickets* Seriously, nothing? :/ )

I liked it! ;)

Quick question - is this case sensitive or insensitive?

On a related note, are we supposed to handle characters that aren't parentheses/brackets, and if so, do those also have to produce a palindrome?

For example, (b]o[b)

How is the string supposed to be input ? I mean, from what I read, nothing prevents me from saying that my program only works when the string is copied in L1 (in Axe) without caring how it got in L1 since the problem is just "check", not "input and check" :P

so, convieniently palindromic for letters, it'd be for "b" and "d", and "p" and "q" ? (also symetrical letters in themselves like "i", "l", "o", "v", "w", "x")

For example : b(][)d is conviniently palindromic, but not b(][)b

Looks harder if we have to handle chars different than brackets :P

I shall change the rules to accomodate those kinds of letter pairs. () {} [] <> /\

I guess TI-83+ implementations should handle two-byte tokens (such as lowercase letters) properly? That seems kind of annoying, but as long as it's consistent among the entries that would be fine with me.

Edit: Actually, case insensitivity would really kill my code (z80 assembly). It's super hard to scan backwards through a token string if you don't know the size the preceding token should be, and I get that size from the token it should match scanning forward.

no chars except the bd and pq should be case sensitive
I agree, that's probably overkill. Either it's sensitive or insensitive, not a mix (although you can try if you want).

Progress on my Golfscript entry:

Returns correct results for all test cases given. The program actually can handle any number of arbitrary pairs. It is now 72.
