Deterministic Select
Deterministic Select Deterministic Select finds the k-th smallest element with guaranteed linear time. It avoids bad pivot choices by constructing a pivot that ensures balanced partitioning. This algorithm is often called the Blum-Floyd-Pratt-Rivest-Tarjan selection algorithm. Problem Given an array $A$ of length $n$ and an integer $k$ with $0 \le k < n$, return the k-th smallest element. Algorithm Divide the array into groups of five, find the median of...
