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;

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

        int count = 0;
        int N = sc.nextInt();
        int[] x;
        x = new int[100];

        for (int i = 0; i < N; i++) {
            x[i] = sc.nextInt();
        }

        for (int i = 0; i < N; i++) {
            int minj = i;
            for (int j = i+1; j < N; j++) {
                if (x[minj] > x[j]) {
                    minj = j;
                }
            }

                if (minj != i) {
                    int temp = x[i];
                    x[i] = x[minj];
                    x[minj] = temp;
                    count++;
                }
        }

            for (int i = 0; i < N - 1; i++) {
                System.out.print(x[i] + " ");
            }
            System.out.println(x[N - 1]);
            System.out.println(count);
    }
