<h3>問題文</h3>
<p>
もうすぐ E869120 君と square1001 君の
<var>16</var> 才の誕生日が来る.<br />
そこで, AtCoder 王国の高橋君は, 円形のケーキ
<var>1</var> 個に放射状に切れ目を入れ
<var>16</var> 等分したものを, 彼らにプレゼントした.
</p>
<p>
E869120 君はそのうち <var>A</var> 切れ、square1001 君は
<var>B</var> 切れを食べようとした.<br />
しかし, ケーキと一緒についていた紙を見ると,
「同じ人が隣り合う
<var>2</var>
切れのケーキを両方取ってはならない」と書かれていた.
</p>
<p>
さて、彼らは紙に書かれたことを守って、<var>2</var>
人とも食べたい数のケーキを取ることができるだろうか？

<h3>Problem Statement</h3>
<p>
E869120's and square1001's <var>16</var>-th birthday is
coming soon.<br />
Takahashi from AtCoder Kingdom gave them a round cake
cut into <var>16</var> equal fan-shaped pieces.
</p>
<p>
E869120 and square1001 were just about to eat
<var>A</var> and <var>B</var> of those pieces,
respectively,<br />
when they found a note attached to the cake saying that
"the same person should not take two adjacent pieces of
cake".
</p>
<p>
Can both of them obey the instruction in the note and
take desired numbers of pieces of cake?
</p>

<h3>Problem Statement</h3>
<p>
Today, the memorable AtCoder Beginner Contest 100 takes
place. On this occasion, Takahashi would like to give an
integer to Ringo.<br />
As the name of the contest is AtCoder Beginner Contest
100, Ringo would be happy if he is given a positive
integer that can be divided by <var>100</var>
<strong>exactly</strong> <var>D</var> times.
</p>
<p>
Find the <var>N</var>-th smallest integer that would
make Ringo happy.

Consider an algorithm that takes as input a positive integer
<span class="math math-inline">n</span>. If
<span class="math math-inline">n</span> is even, the algorithm
divides it by two, and if
<span class="math math-inline">n</span> is odd, the algorithm
multiplies it by three and adds one. The algorithm repeats this,
until <span class="math math-inline">n</span> is one. For example,
the sequence for <span class="math math-inline">n=3</span> is as
follows:
<span class="math math-display">
3 \rightarrow 10 \rightarrow 5 \rightarrow 16 \rightarrow 8
\rightarrow 4 \rightarrow 2 \rightarrow 1</span

Your task is to simulate the execution of the algorithm for a
