Understanding Quick Sort: A Divide-and-Conquer Improvement Over Bubble Sort
Quick sort improves on bubble sort by using a divide‑and‑conquer partitioning strategy, selecting a pivot to recursively sort sub‑arrays, achieving an average time complexity of O(n log n) and a worst case of O(n²), with a vivid “hole‑filling” analogy to illustrate the process.
