Problem

Let SS be the number of answers submitted during the contest. A submission whose position in that order appears in the list below has its penalty reduced by the listed amount. Anything that compiles counts as correct.

  • submission number S/2\lfloor S/2 \rfloor: 200
  • submissions S/21\lfloor S/2 \rfloor - 1 and S/2+1\lfloor S/2 \rfloor + 1: 150
  • submissions S/22\lfloor S/2 \rfloor - 2 and S/2+2\lfloor S/2 \rfloor + 2: 100
  • submissions S/23\lfloor S/2 \rfloor - 3 and S/2+3\lfloor S/2 \rfloor + 3: 50
  • submissions S/24\lfloor S/2 \rfloor - 4 and S/2+4\lfloor S/2 \rfloor + 4: 10

This judge compares output character by character. Of the many answers the original rule accepts, only the lexicographically smallest one counts here. That answer is the empty output.

Input

The input may be empty, or it may hold any number of lines with arbitrary contents. Reading it is optional, and its contents do not change the answer.

Output

Print nothing.
