Sorting
Sorting is the process of arranging data in a specific order, typically ascending or descending. It helps improve search efficiency, data organization and overall algorithm performance. Common sorting algorithms include Bubble Sort, Merge Sort, Quick Sort and Insertion Sort. Sorting is widely used in databases, applications and system processes to manage and analyze information effectively.
