Well, I was wrong. This is football.

Hello, Just to restart the discussion, as we have seen in the previous editions, the Confederations Cup winner did not won the World Cup, however, I bet for Spain to win both tournaments. Football is a complex game (and so why it is awesome), everything can happen in a game. Today Brazil can beat so...

Thanks, man I've found one CAS implemetation on the file /usr/include/asm/system.h of old slackware 10.2 kernel 2.4.31 and it did works. So I just copy it to my project and voilà. Here is the CAS code that worked well for me: #ifndef CAS_H #define CAS_H #define LOCK_PREFIX "lock ; " struct...

Hi there,
I'm here to find some implementation of work-stealing deques without using locks. If anyone of you got one please post it here. It will help me a lot.

Hello,
is there some kind of compare and swap function or macro available in GNU gcc for linux?
I'm trying to implement a lock-free work-stealing queue...

Thanks

Hello,
Have you heard about Maximum distinguished ones?
Can you give some URL, explain or algorithm for that?

Thank you

I am sorry. This code was from my friend and it was wrote in Portuguese, so I translated it to English for post here, but as you could see, I forgot some functions... The message "overflows the recurse stack" does not occurs, but the program craches... My friend did use TurboC, so he paint...

Thanks, did works and I got AC!

Hello, I need some help to fill any polygon (concave or convex). The function must receive one point (x,y) inside the shape. I've tried the recurse solution: void fillpoly(int x, int y, int color) { putpixel(x,y,color); if (getpixel(x-1,y) == BLACK) fillpoly(x-1,y,color); if (getpixel(x+1,y) == BLAC...

Hello,

Can I read the input for this problem this way?
If no, why? Thanks.

thanks, but I know that and I used #ifndef, #define and #endif in my codes, I just have cut out it to simplify my examples...

hello, I want a friend function void set_prob( Combinadic &comb ) to be friend of a class Combinadic . but class Combinadic is splited in two files (combinadic.h and combinadic.cpp). set_prob is extern on a namespace in other file (wildcat.h) and must be implemented in file probability.cpp. it m...

so can you help me?

ok, I've submitted my code with some modifications: int str_nocase_cmp( const char *a, const char *b ) { int i(0); while( a[i] && b[i] ) { if( a[i] >= 'a' && a[i] <= 'z' && b[i] >= 'A' && b[i] <= 'Z' ) { if( (a[i]-32) > b[i] ) return 1; else if( (a[i]-32) < b[i] ) ret...

thanks, so
should I implement some function like str_insensitive_case_cmp?
