0612 TV w/ NERDfirst — Nov 6, 2025 — tutorial
Why watch
A practical tutorial explaining the Quickselect algorithm for finding the kth smallest element in an unsorted list with O(n) average time complexity. The video derives Quickselect from Quicksort's partitioning scheme, provides Python implementation, and analyzes time complexity. Ideal for developers and CS students learning algorithmic efficiency and selection problems.
