Selection Sort Explained Simply — Algorithm, Code & Complexity
The article explains the Selection Sort algorithm, highlighting its efficiency in minimizing swaps during sorting. It provides a step-by-step example of sorting an array and includes a JavaScript implementation of the algorithm. Additionally, it compares Selection Sort with Bubble Sort in terms of stability and swap efficiency.
- ▪Selection Sort performs at most n-1 swaps, making it efficient in systems where writes are costly.
- ▪The algorithm works by repeatedly finding the minimum element from the unsorted portion and moving it to the front.
- ▪A JavaScript function for Selection Sort is provided, demonstrating its implementation.

In systems where writes are expensive, this matters. 🧠 The Core Idea Every pass: scan the unsorted region, find the minimum, swap it to the front. Analogy: Sorting 30 answer sheets by roll number.
