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

1 2 3 4 5 6
4

Sample Input 2

6
5 2 4 6 1 3

Sample Output 2

1 2 3 4 5 6
3

Solution in C# (judge verdict: Accepted)

using System;
using System.Collections.Generic;
using System.Linq;


namespace ALDS1_2_B_Selection_Sort
{
	class Program
	{
		static void Main ( string[] args )
		{
			int numCount = int.Parse (Console.ReadLine ().Trim ());
			int[] numArray = Console.ReadLine ().Trim ().Split (' ').Select (x => int.Parse (x)).ToArray ();

			int swapCount = 0;

			for (int index = 0; index < numCount; index++)
			{
				int minIndex = index;

				for (int index2 = index; index2 < numCount; index2++)
				{
					if (numArray[index2] < numArray[minIndex])
					{
						minIndex = index2;
					}
				}

				if (index != minIndex)
				{
					var tmp = numArray[index];
					numArray[index] = numArray[minIndex];
					numArray[minIndex] = tmp;

					swapCount++;
				}
			}

			for (int lp = 0; lp < numArray.Length - 1; lp++)
			{
				Console.Write (numArray[lp] + " ");
			}
			Console.WriteLine (numArray[numArray.Length - 1]);

			Console.WriteLine (swapCount);
