Coding Challenge
-
Back in the Days of Yore we had a couple of small coding challenges such as the Lean and Mean comp. I was thinking that there are a ton of small, well defined problems that can be tackled a zillion ways in a zillion languages and that it would be cool to see what you guys can come up with. I'd like to start the ball rolling with the following simple task: Problem: Given a string of text, trim from each end of the text each all occurrences of a given set of strings Sample input: Input string: "dog cat monkey dog horse dog" Strings that need to be trimmed from each end: { "dog", "cat" } Final output should be: " monkey dog horse" Final output should be " cat monkey dog horse " [Edit: My final sample output was incorrect, so to be fair I'll accept either answer] It's up to you whether you worry about case sensitivity. Let's see who can provide the smallest, neatest most elegant, most unique and/or fastest code. For those who feel like jumping on the "No Programming questions" bandwagon, please re-read the lounge guidelines. The point of this is to have fun, not to solve each other's programming issues.

Hey Chris, may I post my own programming issue labeling it with 'Coding Challenge' or 'Fun For Everyone'? Just Kidding! Sorry for my poor understanding of English, with

Actually, he said earlier in the post "each end", so he is indicating that it is from both sides. What this shows - Chris sucks at coming up with program specifications. :)

[My articles]I've updated the extremely rigourous and well planned specs to change "either" to "each" and to also show the final output string (so yes: " monkey dog horse ")

Either means both, well, each of two - or it did in its original 'Ye Olde English' version.
Every man can tell how many goats or sheep he possesses, but not how many friends.
No, it means "one or the other".

can we assume the input string is going to be tokenizable on ' ' ? or, should we expect things like "dogcatcotblahfoodog"

How can anything be described as "Most Unique"? Unique is an absolute, it either is or isn't. Perhaps "Most Elegant" would be a more apposite epithet?

How should whitespace at the ends of the input string be treated - does " cat dog " match or only "cat dog"?

Chris barely posted and already there is a design review, rejects from marketing, the devs want to shoot the PM. The PM is whistling nastily (Nagy you dog ... cat... horse... dog) and the mischievous ones reach for the assembler books. What we miss here is QA and we can start a death-march :laugh: EDIT-------------------------- I forgot legal as well. Legal department share its thoughts here with the assistance of the tech writers ;P
