I have made submission to the following problem <a href="https://www.hackerearth.com/january-clash-16/algorithm/rebuild/description/#c45102"> Rebuild (January Clash Contest)</a>. I have made the following submission at first <a href="https://www.hackerearth.com/january-clash-16/algorithm/rebuild/description/#c45102">link here</a> and got following result.↵

<p> I am still not convinced with whatever happened to me. After all what possible differencethat an "equal to" can cause in this case. Please explain ? </p>
