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: WA: Presentation Error)

import java.util.Scanner;

public class Main {

    static int selectionSort(int A[],int N){
        int count = 0;
        for (int i = 0; i<N-1;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){ count++;}
        }
        return count;
    }


    public static void main(String[]args){
       int A[] = new int[100];
        int count = 0;
        Scanner scanner = new Scanner(System.in);
        int N = scanner.nextInt();
        for (int i = 0; i<N; i++){
            A[i] = scanner.nextInt();
        }
        count = selectionSort(A,N);

        for (int i = 0; i<N; i++){
            if (i>0){
                System.out.println();
            }
            System.out.print(A[i]);
        }
        System.out.println();
        System.out.print(count);
    }
