      <description>&lt;h2 id=&#34;ross-littlewood-paradox&#34;&gt;Ross-Littlewood Paradox&lt;/h2&gt;&#xA;&lt;p&gt;Ross has a vase. Littlewood has many small balls; one for each natural number&#xA;$1, 2, 3, \dots$&lt;/p&gt;&#xA;&lt;p&gt;Littlewood first drops balls $1, 2, \ldots 10$ into the vase. Ross does not like&#xA;that. The incident triggers the following game to start. In the game, Ross and&#xA;Littlewood take alternating turns. In a round, Ross goes first then Littlewood&#xA;responds.&lt;/p&gt;&#xA;&lt;p&gt;First round: Ross is mad about the balls so he removes ball $1$ from the vase.&#xA;Littlewood responds by dropping in balls $11, 12, \ldots 20$. Second round: Ross removes ball&#xA;$2$. Littlewood responds again, dropping balls $21, 22, \ldots 30$.&lt;/p&gt;</description>
