Selection Sort Complexity

The video tutorial explains the complexity of selection sort, focusing on its O(n^2) complexity. It uses two loops, resulting in n^2 iterations. A mathematical explanation is provided, showing the series n(n-1)/2, which simplifies to n^2/2 - n/2. The video discusses best, average, and worst-case scenarios, all resulting in O(n^2) complexity. The tutorial concludes by emphasizing the importance of understanding selection sort's complexity and encourages viewers to revisit the material if needed.
