UVA10827 Maximum sum on a torus WA

I wrote a O(n^4) solution for UVA10827. It passes all the tests on udebug and the ones that I can find from past threads on this problem. Unfortunately, I am still getting WA. Is anyone able to come up with a counterexample for my algorithm? #include <iostream> #include <algorithm> using namespace s...

Could someone please help me? class Main { public static void main(String[] args) { java.util.Scanner in = new java.util.Scanner(System.in); long[] sides = new long[3]; long cases = in.nextLong(); String...

The following is the offending block of code: /* process the configuration */ for(index = 0; index < num_trains - 1; in...

Re: 514 Rails: WA

Yeah. All the other solutions that I saw also used a Stack. But why is my logic wrong?

514 Rails: WA

I did this problem in a different way from the rest. I saw that others were using stack to simulate the process but I used a general observation that I made to solve this problem (which is, if there is a larger preceding number in front of a later number, then the later number and its consecutive se...

Re: 462 - Bridge Hand Evaluator

Hi. Thanks for your help. I managed to get AC at last! Yeah, I know that the there is another thread regarding the same problem already. But I just could not spot any logic errors. So I though that maybe someone could help me with debugging. I collected all the test cases and I checked the input tha...

462 - Bridge Hand Evaluator

Hi all. I have carefully crafted and refined my algorithm many times. But I can''t seem to see where the error lies. I just keep getting WA. See my code below: import java.util.*; class Main { public static void main(String[] args) { Scanner in = new Scanner(System.in); LinkedList<Card> arr = null; ...
