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

Sample Input 1

6
5 6 4 2 1 3

Sample Output 1

1 2 3 4 5 6
4

Sample Input 2

6
5 2 4 6 1 3

Sample Output 2

1 2 3 4 5 6
3

Solution in JAVA (judge verdict: Wrong Answer)

import java.io.*;

public class Main {
  public static void main(String[] args) {
    try {
      BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
      int count = Integer.parseInt(in.readLine());
      int[] iArr = new int[count];
      String[] sArr = in.readLine().split(" ");
      for(int i=0; i<sArr.length; i++) {
        iArr[i] = Integer.parseInt(sArr[i]);
      }
      int swapCount = 0;
      for(int i = 0; i < iArr.length; i++) {
        int minj = i;
        for(int j = i; j < iArr.length; j++) {
          if(iArr[j] < iArr[minj]) { minj = j; }
          int tmp = iArr[minj];
          iArr[minj] = iArr[j];
          iArr[j] = tmp;
          swapCount++;
        }
      }
      StringBuilder sb = new StringBuilder();
      for(int i : iArr){
        sb.append(i).append(" ");
      }
      System.out.println(sb.toString().trim());
      System.out.println(swapCount);
    } catch (IOException e) {}
  }
