Problem:
Selection Sort

Write a program of the Selection Sort algorithm which sorts a sequence A in ascending order. The algorithm should be based on the following pseudocode:

SelectionSort(A)
1 for i = 0 to A.length-1
2 mini = i
3 for j = i to A.length-1
4 if A[j] < A[mini]
5 mini = j
6 swap A[i] and A[mini]

Note that, indices for array elements are based on 0-origin.

Your program should also print the number of swap operations defined in line 6 of the pseudocode in the case where i ≠ mini.

Input

The first line of the input includes an integer N, the number of elements in the sequence.

In the second line, N elements of the sequence are given separated by space characters.

Output

The output consists of 2 lines.

In the first line, please print the sorted sequence. Two contiguous elements of the sequence should be separated by a space character.

In the second line, please print the number of swap operations.

Constraints

1 ≤ N ≤ 100

Solution in C# (judge verdict: Wrong Answer)

using System;

class Program
{
    static void Main()
    {
        int n = int.Parse(Console.ReadLine());
        string[] s = Console.ReadLine().Split(' ');
        int[] a = new int[n];
        for (int i = 0; i < a.Length; i++)
            a[i] = int.Parse(s[i]);

        int count = 0;
        for(int i = 0;i < a.Length; i++)
        {
            int minj = i;
            for (int j = i; j < a.Length; j++)
            {
                if (a[minj] > a[j])
                {
                    minj = j;
                }
            }
            if (a[i] != a[minj])
                count++;

            int tmp = a[i];
            a[i] = a[minj];
            a[minj] = tmp;
        }

        foreach (int x in a)
        {
            if (x == a[a.Length - 1])
                Console.WriteLine("{0}", x);
            else
                Console.Write("{0} ", x);
        }
        Console.WriteLine(count);
    }
}
