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: Wrong Answer)

import java.util.Scanner;

class Main {
  public static void main(String[] args) {
  	Scanner sc = new Scanner(System.in);
  	int n = sc.nextInt();
  	int[] a = new int[n];
  	for(int i = 0; i < n; ++i){
  		a[i] = sc.nextInt();
  	}
  	
  	int num = 0;
  	for(int i = 0; i < n; ++i){
  		int minj = i;
  		for(int j = i; j < n; ++j){
  			if(a[minj] > a[j]){
  				minj = j;
  			}
  		}
  		int tmp = a[minj];
  		a[minj] = a[i];
  		a[i] = tmp;
  		num = num + 1;
  	}
  	for(int i = 0; i < n; ++i){
  		System.out.print(i == 0 ? a[i] : " " + a[i]);
  	}
  	System.out.println();
  	System.out.println(num);
  }
