output_description: If the total value of N bills cannot be Y yen, print `-1 -1 -1`.
  
  If the total value of N bills can be Y yen, let one such set of bills be "x
  10000-yen bills, y 5000-yen bills and z 1000-yen bills", and print x, y, z
  with spaces in between. If there are multiple possibilities, any of them may
  be printed.

problem_description: Statement
  
  The commonly used bills in Japan are 10000-yen, 5000-yen and 1000-yen bills.
  Below, the word "bill" refers to only these.
  
  According to Aohashi, he received an otoshidama (New Year money gift) envelope
  from his grandfather that contained N bills for a total of Y yen, but he may
  be lying. Determine whether such a situation is possible, and if it is, find a
  possible set of bills contained in the envelope. Assume that his grandfather
  is rich enough, and the envelope was large enough.
