A Voyage through Algorithms using Javascript - Quick Sort
- Quick Sort is a widely-used sorting algorithm known for its efficiency in computer science.
- It follows a 'divide and conquer' approach by selecting a 'pivot' element and partitioning the array around it.
- Quick Sort has an average-case time complexity of O(n log n) and is capable of in-place sorting.
- However, its performance can degrade to O(n²) in worst-case scenarios, emphasizing the importance of pivot selection.
- The algorithm recursively sorts sub-arrays on both sides of the pivot until everything is organized.
- Quick Sort implementation in JavaScript involves selecting a pivot, partitioning, and recursive sorting.
- The algorithm works by creating an invisible boundary and organizing elements in-place within the same array.
- Quick Sort is not stable and can change the relative positions of equal elements during partitioning.
- Its performance heavily depends on pivot selection, with good pivots leading to balanced partitions and optimal performance.
- Advantages of Quick Sort include excellent average-case performance, in-place sorting, and cache efficiency.
- Quick Sort is suitable for general-purpose sorting, memory-constrained environments, and performance-critical applications.
