Motivation
Lesson 2 of 9 in Coddy's Selection Sort - DSA Series course.
Selection Sort works by splitting the array into two parts: a sorted part on the left and an unsorted part on the right. On every pass it selects the smallest element from the unsorted part and places it right after the sorted part.
Why learn Selection Sort?
- Simplicity: it is one of the easiest sorting algorithms to reason about.
- In-place: it sorts the array without needing extra memory.
- Few swaps: it performs at most one swap per pass, which matters when writing to memory is expensive.
- Foundation: it builds intuition for more advanced sorting techniques.
