Re: [Haskell-beginners] Help with improving a program

Thanks for all the replies, I really liked Florian's answer, even though, if I were to adopt that style, I think the haskell gods would shunne me for using mixing too much pure and impure code. On 07/10/2014 10:24 AM, Florian Gillard wrote:

I don't know if this is any good but here is my attempt to solve this.

I used comprehensions.

It seems to be working fine with the test files :)

Hi I'm just starting with haskell and want some help with it.

I tried to solve the Store Credit[1] problem from google code jam just to practice, the result was a slow code[2] that I find hard to read.

Can you guys give me some directions on how to improve it?

Don't know about efficiency, but I never liked (!!). Maybe computing all pairs+positions in advance using |zip| would be a little better?

Yeah, that's what I went for as well. I'm attaching my solution for comparison to this mail.
