Ok I got it but I get PE...
Anything wrong on my output??
Here is output code:

for(i=0; i<n; i++)
{
sum=0;
for(j=0; j<n; j++)
{
sum+=matrix[j][i];
if(matrix[j][i]!=0)
{
zerocounter++;
}
}
cout<<p[i].name<<" ";
if(zerocounter==0)
{
cout<<0;
}
else
{
cout<<sum-capital[i];
}
cout ...

Ok I got WA...
What the h.....???

Any body??

How about a special case:
There is a post on this forum discussing the following input/output:
Input:
2
a 10 0
b 10 0

I'm about to submit my code, and according to it, it will print a -10 and b-9.
Why?
Simple:
a spends 10 and b spends 9. They both received 0, so they lost 10 and 9 recpectively. It ...

Ok thanks anyways guys.
I finally got ACC, I used dynamic memory and also my method for finding all triples is quite fast, like O(nlogn).

I submitted this program more than 30 times and always got WA or RE and it was because of the arrays thing, so be carefull.

Thank you.

I'm so happy!!!!!

Here is my code, if you test in your computer you will see that it gives the correct answer for every input, but the judge keeps replying WA....

What is wrong?????


#include <iostream>
#include <cmath>
using namespace std;
struct triple
{
int x, y, z;
};
void q_sort(triple numbers[], int ...

Hi there.
I'm very sad.
My program runs in 10.1 sec which is only 0.1 sec more than the limit for this proglem....

Here is my code, which I'll romove soon.
Hope somebody gives me a hint...

#include "stdafx.h"
#include <iostream>
#include <cmath>
using namespace std;
struct triple
{
double x, y, z ...

Oooppppsssssssssssss.............
You are right.
Thanks so much. I guess then my method for finding all triples(not just primitive triples is wrong).

This is what I do for that:

loop a) starts at 1 and keeps going as long as i^2 + (i+1)^2 <=n

nested loop b) starts at i+1 and keeps going as long ...

I need some serious help. Unless I'm blind I think sample is wrong.
Here is why:

Input: 25

There are only 4 primitive triples: (3, 4, 5), (15, 8, 17), (5, 12, 13), and
(7, 24, 25).
This is ok, so answer to the first question is fine.

But second part I think it's wrong and here is why:
Besides the ...
