マーティン・ガードナーの最難問を解くPython Script
解けるかな？ 史上最難問10題 : ギズモード・ジャパン http://www.gizmodo.jp/2013/08/_so_you_th.html?utm_source=rss20&utm_medium=rss
ある数の粘度は、すべての桁を掛けて出る答えが1桁になるまでにかかる積算の回数で表す。
それぞれの桁の数を掛け算して出るのが2番目の数で、そのまた全桁の数を掛けて出るのが3番目の数…こうして1桁の数が出るまでやり、
出るまでに重ねた掛け算の回数を数えるのだ。
例えば、77は粘度4だ。なぜなら1桁になるまで4回掛け算しなきゃならないからね（77-49-36-18-8）。
