ソートアルゴリズム
データを特定の順序で配置するアルゴリズム。
Sorting is one of the most fundamental operations in computing. Sorting algorithms organize data to make searching and processing more efficient. Common examples include Quicksort, Mergesort, and Heapsort. The efficiency is measured in Big O notation, focusing on time and space complexity.

Sorting is like putting a messy pile of books in order from A to Z on a shelf. Some ways are faster than others, but they all finish with a neat, organized line of books.
🤓 Expert Deep Dive
Stability in sorting ensures that elements with equal keys maintain their relative order. In-place algorithms (like Quicksort) use minimal extra memory. Comparison-based sorting is limited to O(n log n) worst-case time, while non-comparison algorithms like Radix Sort can achieve linear time in specific conditions.
