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 in = new Scanner(System.in);
		int numSwaps = 0;
			
		int n = in.nextInt();
		int [] arr = new int [n];
		
			
		for(int i = 0; i < n; i++) {
				arr[i] = in.nextInt();
			}
		
		
			
		for(int j = 0; j < n; j++) {
			
			int minIndex = j;
			
			for(int h = j + 1; h < n; h++) {
				if(arr[h] <arr[minIndex]) {
					minIndex = h;
				}
			}
			
			if(j != minIndex) {
				int temp = arr[j];
				arr[j] = arr[minIndex];
				arr[minIndex] = temp;
				numSwaps++;
			}
		}
		for(int k = 0; k < n; k++) {
			System.out.print(arr[k]);
			
			if(k != n - 1) {
				System.out.print(" ");
			}
		}
		System.out.println("\n" + numSwaps);
	}
