Hello!
 In the description of the input data written:
 The number n is written without a decimal point. All other numbers are written with not more than two digits after a decimal point (if a number is integer a decimal point may be omitted). All the input numbers are non-negative not greater than 1000.
 But in the tests (for example, test N7) there are number with more then 2 digits after a decimal point. Please, make the tests correct, or change the problem description.

Why do you think so?

Tests are correct. All numbers have no more than two digits after a decimal point.

I wrote code like this (in reading data):

 scanf( "%lf", &x );
 if( fabs( int(x*100)-x*100 )>1e-2 )
  throw 0;

and my program have been crashed.

double x = 4.02;
printf("%.2lf %.2lf\n", x, int(x*100)-x*100);
