Input modifications:

For testing of submited solutions purpose we extended input specification.
Each input contains more than one testing cases:

Problem A - Each testing case begins with the number of points. 
            Zero number of points means end of input.
Problem B - No change.
Problem C - No change.
Problem D - More testing cases. Zero number of straws means end of input
Porblem E - First number on the input is the number of cases. Each case ends
            with two -1.
Problem F - No change.
Problem G - No change.
Proglem H - More testing cases separated by empty line.
    

Errata:

Problem B - * our b_gen.c generates wrong input b.in (contains excluded 
              characters and empty lines)

Problem E - * empty item number 2 should be removed. The item 3 should be
              number 2.
            * "_1's" should be "-1's".
            * picture omitted.
