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: Accepted)

using System;

class Program
{
    static int[] a;

    static void Main(string[] args)
    {
        int n = int.Parse(Console.ReadLine());
 
        a = new int[n];
 
        string[] input = Console.ReadLine().Split(' ');
        for (int i = 0; i < a.Length; i++)
        {
            a[i] = int.Parse(input[i]);
        }
 
        SelectSort();
    }
 
    static void SelectSort()
    {
        int count = 0;
 
		for (int i = 0; i < a.Length; i++)
		{
			int min = i;

			for (int j = i+1; j < a.Length; j++)
			{
				if (a[j] < a[min])
				{
					min = j;
				}
			}

			if (i != min)
			{ 
				int buf = a[i];
				a[i] = a[min];
				a[min] = buf;

				count ++;
			}
		}
 
        string output = "";
        for (int i = 0; i < a.Length; i++)
        {
            output += a[i] + ((i == a.Length-1) ? "" : " ");
        }
 
        Console.WriteLine(output);
        Console.WriteLine(count);
    }
}
