100
整数n を受け取り、2 進数に変換した結果を保持する変数を宣言します。
10進数は1の位、10の位、100の位、……と表されるように、2進数も 2^0の位、
2^1の位、2^2の位、……と表すことができ、2の累乗ごとに桁が上がっていきます。

例えば、10進数の各桁の数字を決めるときのことを考えてみましょう。ある10
進数の値を10で割ったときの余りを10^0の位(1桁目)の数字とし、商をさらに10
で割った余りを 10^1の位(2桁目)の数字とする……という処理を繰り返すことで、
各桁の数字が決まります。
2進数の場合も同じように考えることができます。ある10進数の値を2 で割った
ときの余りを2^0の位(1桁目)の数字とし、商をさらに2で割った余りを ...
