Summary
The video provides a detailed explanation of the selection sort algorithm for sorting an array in increasing order by selecting the smallest item during each iteration. It showcases the process of setting the current minimum, finding smaller numbers, and swapping them to arrange the array. The demonstration underscores the importance of updating the current minimum and preparing for the next iteration. The video concludes with a presentation of the pseudocode for the selection sort algorithm and a discussion on its time complexity based on the array size.
