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

Sample Input 1

6
5 6 4 2 1 3

Sample Output 1

4

Sample Input 2

6

Sample Output 2

1 2 3 4 5 6
3

Solution in C# (judge verdict: Wrong Answer)

using System;
using System.Linq;

namespace Sort_I
{
    class Selection_Sort
    {
        static void Main(string[] args)
        {
            Console.ReadLine();
            var A = Console.ReadLine().Split(' ').Select(s => int.Parse(s)).ToArray();
            var n = SelectionSort(A);
            for (int i = 0; i < A.Length - 1; i++)
            {
                Console.Write(A[i] + " ");
            }
            Console.WriteLine(A.Last());
            Console.WriteLine(n);
        }

        static int SelectionSort(int[] A)
        {
            var n = 0;
            for (int i = 0; i < A.Length; i++)
            {
                var minj = i;
                for (int j = i; j < A.Length ; j++)
                    if (A[j] < A[minj])
                        minj = j;

                var temp = A[i];
                A[i] = A[minj];
                A[minj] = temp;
                n++;
            }
            return n;
        }
    }
