Introselect
Introselect Introselect is a hybrid selection algorithm. It starts with Quickselect for speed and switches to a worst-case linear method when recursion becomes too deep. This design mirrors Introsort. The goal is to keep the fast average behavior of Quickselect while guaranteeing linear worst-case time. Problem Given an array $A$ and integer $k$, find the k-th smallest element with both practical efficiency and worst-case guarantees. Algorithm Run Quickselect with a...
