TIFR CSE 2013 | Part B | Question: 18
Let $S$ be a set of numbers. For $x \in S$, the rank of $x$ is the number of elements in $S$ that are less than or equal to $x$. The procedure $\textsf{Select}(S, r)$ takes a set $S$ of numbers and a rank $r\left(1 \leq r \leq |S|\right)$ and returns the ... $|S|$ constant · $|S||R|$ constant · $|R| \log |S|$ constant · $|S|(1 + \log |R|)$
