The algorithm is the perceptron algorithm. I believe it can be cast as gradient descent.

hey cormac look below:
the problem said for the last test case should be: 0 0
but the judge data has no input like 0 0
now for this coding technique you will get wa in this problem

#include<stdio.h>
int main()
{ long i,n,q;
char c;
while(scanf("%ld%ld",&n,&q)==2)
{ if(n==0&&q==0)
break;
for(i ...

thnx cormac for reply

i got WA with my code several times
but few minutes ago when i delete the while condition and delete the breaking condition from my code i got AC.

So why i cant i say that the judge data is faulty
when it doesnot work when i wrote like this:

while(scanf("%ld%ld",&n,&q)==2 ...

hey cormac
i
so i have to ready a program after a lot of thoughts
but when it comes WA for poor judge data (for giving the breaking conditions) it really frustrated us.

If you got WA it is because your program is wrong.

By weak data, I mean that the judge gives AC when it ...

FROM NOW I WILL FIRST SEND THE SAMPLE OUTPUT BEFORE SUBMITTING ANY PROBELMS
WHO KNOWS IF THE PROBELM HAVE SINGLE INPUT WITHOUT BREAKING CONDITION(!!!!!!!!!!!!!) :wink:

In a contest that'll cost you points.

This is a practice site. I don't see that developing strategies to spoof the judge gives ...

ok
when garbage is accepted with some garbage output
then it may raise question about the judge data.

strange
really strange that how a garbage code can have a AC.

[I had made a comment saying that Waterloo had 20 test cases where uva.es had only one. I was mistaken. uva.es should have all test ...

thnx cormac for reply

this is the link of that code:

it got ac in UVA but result "bad luck" for the test case...
i will remove the link after your message....

thnx baodog for your reply
i didn't found any additional I/O but i found a source code of wedding which is found as a AC code when it is tested.

then i make some sample input to compare it with my own source code:
input:

10 2
1h 2w
1h 2h

for which my own code's output is:
1h 2h 3h 4h 5h 6h 7h 8h ...

What I did was -
1. Find the number of knights that will get a bye .

Let the number of knights that didn't get a bye = M.

2. Then I sorted all the <name, ability> in increasing order of ability.

Isn't it true that the best selection of M knights would be a consecutive subsequence?

This method ...

Now if, for example, A plays B, the winner plays C, and the winner plays D, we have the case that A needs to play in 3 events to win. So it is not true that no knight must compete in more than 2 events, because A must. So this second schedule fails to maximize e.
Well, 4 knights, A, B, C, D. A ...

The problem states..
The tournament schedule is organized so that no knight needs to compete in more than e events to be champion, for the minimum possible e given k, the number of knights.
The minimum possible e should be always 1. So, the number of knights can be reduced to 2. Am I right or I ...

integral is nasty, but it has a simple solution to find the volume of a cone sliced by a plane parallel to its axis. First you to find of area of the base of a cone(segment of the base circle) and multiply to height(not height of con) and devide it 3
R - radius of a cone
h - height of a cone
t,p ...

Please help me, i tested it with several test case, but it was WA
here is my code

thanks

Not sure what you are doing but I don't see any code that integrates to find the volume of a cone sliced by a plane parallel to its axis. This integral is nasty. Dr. Math has an incorrect solution and I have ...
