B_S_C_S - Biggest sum of a coherent subsequence
|Wersja polska||English version|
Your task is to find the biggest sum of a coherent subsequence.
There is an unknown number (less than 105) of integers which are less than 109.
One single number which is the biggest sum of a coherent subsequence.
1000 -100 5 -8 4 -100 1000

@Piotr: Thanks - I'll have to have a good think on that. I wasn't completely satisfied that the 2nd half was optimal, but obviously it's linked into the first half too by your comment :-)
That is sneaky! But funky at the same time.

Both, but more the second half. ;-)
Good luck. :-)

Hmm. At the moment I can't see how to implement the same algorithm in a shorter manner. I think I might need to take a break and look at this again with fresh eyes :-)
Cheeky question - first half, or second half that would need to be changed? :-)

@Jander - Implementation, sorry for the confusion.

@Piotr - I figured my solution was somewhat different to clytorock's and yours due to the time taken to run. But I didn't think they were *that* different. I take it that we're using the same algorithm, just a different implementation ?

challenger is my account. I made it of course to increase the rivalry.
I look at users' codes and comparing few of them I try to remove some bytes (not change the algorithm). Comparing Your and clytorock's code I managed to change his program without changing the algorithm. So You would have to change half of Your program to reach 33 chars.
But without challenger many users wouldn't even try to shorten their best results as they would think that it's impossible. I'm to show that they're wrong. ;-)

As usual challenger, I'm amazed at how you manage to remove that one extra byte :-) How you do it, I have no idea.

what's the catch here? i seem to be covering all the cases and still i get WA.
