challenge ビンゴの結果を整形表示

「重複無し乱数」の続編です。

「重複無し乱数」で作ったbingo関数の結果を下のように「何番目の乱数か」とセットにして10個ずつ折り返して表示するコードを書いてください。

showBingo に (length x) を渡したけど、
(length (show n))を渡す方がよいかもです。

表示方法のみの変更なので show() 関数だけ変更

僕が出題前に書いたコードはこんな感じですが、
確かに#2324みたいにrangeのstepを使った方がいいですね。
スライシングで添え字の範囲が超えてもエラーにならないので僕のコードの18行目以降みたいな
「1行に満たない残りがあれば表示」というコードがいらなくなるわけですね。

	  表示桁指定は * でできますが、表示桁の求め方を 2 種類用意しました。

1. libm をリンクして、log10 を使う方法

2. stderr を捨てて fprintf を使う方法

「重複無し乱数」で投稿したものを手直ししました。そろそろバッチでできることの限界
が見えてきたような気がします。

  e.g.
    C:\>bingo 30
      1  2  3  4  5  6  7  8  9 10
      6 14  2 13  4 28 20  9 12 16

     11 12 13 14 15 16 17 18 19 20
     26 15  1 30 21 25 27 22 19 29
    
     21 22 23 24 25 26 27 28 29 30
      3 23 10 24  5 18 11 17  7  8

    C:\>bingo 35
      1  2  3  4  5  6  7  8  9 10

     33  5 35  1 15 21  3 32 26 22
