考え方

剰余の求め方
iの３の剰余が０ならばskip0へ飛ぶ。

  push  "i"
  get
  push  "3"
  %
  push  "1"
  >
  if  skip0

サンプルコード

  push  "x"
  push  ""
  set
  push  "i"
  push  "0"
  set
loop  push  "i"
  push  "i"
  get
  ++
  set
  get
  push  "i"
  get
  push  "15"
  %
  push  "1"
  >
  if  skip2
  push  "i"
  get
  push  "5"
  %
  push  "1"
  >
  if  skip1
  push  "i"
  get
  push  "3"
  %
  push  "1"
  >
  if  skip0
  push  "x"
  push  "x"
  get
  push  "i"
  get
  add
  set
  push  "x"
  push  "x"
  get
  push  " "
  jp  skip3
skip0  push  "x"
  push  "x"

  jp  skip3
skip1  push  "x"
  push  "x"
