Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

The following is the selection sort
public class Selection
{
public static void sort(Comparable[] a)
{
int N = a.length;
for (int i = 0; i < N; i++)
{
int min = i;
%3D
for (int j = i+1; j < N; j++)
if (less(a[j], a[min]))
min = j;
exch (a, i, min);
}
}
1- Explain the code line by line
2 - what is the worst number of required exchanges for sorting an array of length N
3 - using Selection sort; sort the numbers 5,1,9,45,0,8 by showing the values i and min in
every iteration
