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 alds12a
{
    static void swap(ref int a, ref int b)
    {
        int tmp = a;
        a = b;
        b = tmp;
    }
    static void Main()
    {
        int  tn=int.Parse(Console.ReadLine());
        string[] input = Console.ReadLine().Split(' ');
        int[] num = new int[tn];
        int count = 0;
        for (int i = 0; tn > i; i++)
        {
            num[i] = int.Parse(input[i]);
        }
        for (int i = 0; tn > i; i++)
        {
            int min = i;
            for (int j = i; j < tn; j++)
            {
                if (num[j] < num[min]) min = j;
            }
            if (i != min)
            {
                swap(ref num[i], ref num[min]);
                count++;
            }
        }
        for (int i = 0; tn - 1 > i; i++)
        {
            Console.Write(num[i]);
            Console.Write(' ');
        }
        Console.WriteLine(num[tn-1]);
        Console.WriteLine(count);
    
    
    }
