What is QuickSelect with Median of Medians about?

The document explains the Median of Medians technique to improve the worst-case performance of QuickSelect from O(n²) to O(n) by ensuring a better pivot selection. It details the steps involved in the algorithm, including dividing the array into groups, finding medians, and partitioning around the chosen pivot. The time complexity is O(n) for average, worst, and best cases, while the space complexity is O(n) due to recursion.
