<PRE><B>Question 1112321</B>
.
I do not know why the tutor &amp;nbsp;@mananth &amp;nbsp;talks about the height of the tower.


Nobody asked in this problems about the height of the tower.


And the problem is &amp;nbsp;&lt;U&gt;ABSOLUTELY &amp;nbsp;IRRELEVANT&lt;/U&gt;&amp;nbsp; to the tower&#39;s height.


It is about totally different thing.


The tutor @mananth misread and misinterpreted the problem, &amp;nbsp;and his writing is &amp;nbsp;&lt;U&gt;I R R E L E V A N T&lt;/U&gt;.
