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;

class main{
    public static void Main(String[] args){

        int n = int.Parse(Console.ReadLine());
        int[] a = Array.ConvertAll(Console.ReadLine().Split(' '),int.Parse);

        int index;

        index = selectionSort(a,n);
        
        for(int i = 0; i < n; i++){
            if(i != n-1){
                Console.Write(a[i] + " ");
            }else{
                Console.WriteLine(a[i]);
            }
        }
        
        Console.WriteLine(index);
    }

    internal static int selectionSort(int[] a,int n){

        int[] A = a;
        int N = n;
        int index = 0;

        for(int i = 0;i < N; i++){
            int minj = i;

            for(int j = i;j < N;j++){
                if(A[j] < A[minj]){
                    minj = j;
                }
            }

            int temp = A[i];
            A[i] = A[minj];
            A[minj] = temp;
            if(i != minj){
                index++;
            }
        }

        return index;
    }
}
