Welcome Geeks, 
 
This is the contest&nbsp;of 12th&nbsp; Day of 21 days problem-solving challenge of interview preparation with GeeksforGeeks.&nbsp;

This contest has 3&nbsp;coding questions based on Queue &amp;&nbsp;Deque&nbsp;and 10 MCQs&nbsp;on Transaction and Concurrency Control. 
 
To simulate a real interview environment, the contest has:

<ul>
	<li>All of the problems are function problems, i.e. you need to complete only a given function rather than writing complete code.</li>
	<li>You can also access hints while solving problems, using hints will deduct marks.</li>
</ul>

Good Luck!
