In what seems like a long-time back, I used to be interested in programming contests. This folder contains the source-code for my solutions at various Online Judges,

• LA - ACM Live Archive

• Spoj - Sphere Online Judge

Please do not copy-paste solutions into the Online Judge.

P.S: Some solutions might be incomplete.

At some point, I remember using someonelse's code for fast reading of integers. I dont know who, but here is that piece of code anyway,

#define ITYPE unsigned int
#define GETCHAR getchar
#define DIG( a ) ( ( ( a ) >= '0' ) && ( ( a ) <= '9' ) )

ITYPE GETNUM ( void ){
  int i ;
  ITYPE j ;

  i = GETCHAR () ;
  while ( ! DIG( i ) )  i = GETCHAR () ;

  j = ( i - '0' ) ;

  i = GETCHAR () ;
  while ( DIG( i ) ) {
     j = ( ( j << 1 ) + ( j << 3 ) + ( i - '0' ) ) ;
     i = GETCHAR () ;
  }
  return ( j ) ;
}
