Forgot about my post above - I had one little error. Now is AC

Unfortunately, still on Windows. I had many problems with my old sound card on RedHat 9, I googled for solution but nothing works. If I won't be so lazy next month may be I will buy sth new an move to Linux

If I clearly understand you, this is finding the 'inversion number' (this algoritm works).

Hmm... Try to change this lines:
[c]/* ... */
while ( scanf ("%d%d%*c", &step, &mod) == 2 )
/* ... */
printf ("%10d%10d Good Choice\n\n", step, mod);
else
printf ("%10d%10d Bad Choice\n\n", step, mod);
/* ... */[/c]
1) scanf - there is no need to read '%*c' <- this * is a bug? Any way you don't ...

Do you include stdio.h?

I count it this way: first I cut off as large number as I can - this is the sum of diagonals = 1+2+3+4+..... (i use sqrt, so my time is 0.006 too). Then I simply calculate the result.

I have gcc & g++ version 3.2.2 (Red Hat 9.0) - and when I compile this on gcc I have an error, on g++ - I have not.
I know it's strange, but it's true

I have tested judge's input of leading and trailing zeroes: and I think there are no test cases with it (but input like '0 0' can be).

But there is a difference. Try to make this: and you won't have any errors.

Can anyone give more sample input & output for this problem? I don't understand cleary when I have to replace zeros (leading zeros after adding, as the problem description says, and I tried to remove and not remove trailing zeros before adding).

You should write the code like this:
[cpp]#include <iostream>
using namespace std;

/* code */

[/cpp]
1) there is no need to include stdio, if you use only cin and cout
2) declaration of iostream was wrong - but this cause only warning message

And the major problem, you calculate the output in ...

You have to put this in your code after including libraries:
[cpp]using namespace std;
[/cpp]

a=new char;

I think this case error: size of a is 1 char only.

I wrote this code to solve the problem without strings. It works fine on my pc generating the correct output for all test cases as compared to the stringed program that got AC. However, the judge says WA. Can anyone help? Pretty please! :oops:

Maybe your problem is in function main() - it has ...

I set this as input:

test
longtest
test

In output in third line was error - it looks like this:

tse'\0'tset
