Java - Selection Sort Algorithm

Question

I have some questions about selection sort.I\'m a little bit confused.

 int [] arr = {5,4,3,2,1}; // This is my array
    int min = 0;

    for(int i = 0;i&l         


        

Answer 1

Your question appears to be in your comment

min = i;//Selection sort algorithm says that find the minimum in the
        // array, but first element is not minimum.What's point here?

The point of that is you can assume the first one you're checking is the lowest just so you have a place to start from. After all, it might not be the minimum over all, but of the one's you've checked in this iteration, it's the lowest so far!
