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);
        StringBuilder build = new StringBuilder();
        int z = sc.nextInt();
        int[] ary = new int[z];
        for(int i = 0 ; i < ary.length; i++){
            ary[i] = sc.nextInt();
        }
        int count = 0;
        for(int i = 0; i < ary.length; i++){
            int min = i;
            for(int j = i; j < ary.length; j++){
                if(i != 0){
                    if(ary[min] == ary[i-1]){break;}
                }
                min = ary[min] > ary[j] ? j : min;
            }
            if(ary[i] != ary[min]){
                int temp = ary[i];
                ary[i] = ary[min];
                ary[min] = temp;
                count++;
            }
        }
        for(int i = 0; i < ary.length; i++){
            build.append(ary[i]);
            build.append(i==ary.length-1 ? "\n" : " ");
        }
        build.append(count);
        System.out.println(build.toString());
