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 JAVA (judge verdict: Accepted)

import java.util.Scanner;

class Main{
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);

        int n = Integer.parseInt(sc.nextLine());
        String[] input = sc.nextLine().split(" ");
        int[] array = new int[n];
        
        for(int i = 0; i < n; i++){
            array[i] = Integer.parseInt(input[i]);
        }

        int count = 0;

        for(int i = 0; i < n; i++){
            int minj = i;
            for(int j = i; j < n; j++){
                if(array[j] < array[minj]){
                    minj = j;
                }
            }
            if(i != minj){
                int tmp = array[i];
                array[i] = array[minj];
                array[minj] = tmp;
                count++;
            }
        }

        StringBuilder sb = new StringBuilder();
        for(int i : array){
            sb.append(i + " ");
        }

        System.out.println(sb.deleteCharAt(sb.length()-1));
        System.out.println(count);
        
    }
