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

Sample Output 1

1 2 3 4 5 6
4

Sample Input 2

6

Sample Output 2

1 2 3 4 5 6
3

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

class Main
{
	public static void main(String[] args){
		Scanner scan = new Scanner(System.in);
		
		int[] a = new int[100];
		int x = 0;
		
		int n = scan.nextInt();
		
		for(int i=0; i<n; i++){
			a[i] = scan.nextInt();
		}
		
		for(int i=0; i<n; i++){
			int min = i;
			int c = 0;
			for(int j=i; j<n; j++){
				if(a[min] > a[j]){
					min = j;
					c = 1;
				}
			}
			int kari = a[i];
			a[i] = a[min];
			a[min] = kari;
			if(c==1){
				x++;
			}
		}
		
		for(int i=0; i<n; i++){
			System.out.print(a[i]);
			if(i!=n-1){
				System.out.print(" ");
			}
			else{
				System.out.print("\n");
			}
		}
		
		System.out.println(x);
	}
