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 C# (judge verdict: Accepted)

using System;

namespace AOJ {
    class ALDS1_2_B {
        static void Main(string[] args) {
            int n = int.Parse(Console.ReadLine());
            string[] input = Console.ReadLine().Split();
            int[] data = new int[n];
            for (int i = 0; i < input.Length; i++) {
                data[i] = int.Parse(input[i]);
            }
            SelectionSort(data, n);
        }

        static void SelectionSort(int[] A, int n) {
            int count = 0;
            for(int i = 0; i < n-1; i++) {
                int minindex = i;
                for(int j = i; j < n; j++) {
                    if (A[j] < A[minindex]) minindex = j;
                }
                int tmp = A[i];
                A[i] = A[minindex];
                A[minindex] = tmp;
                if(i!=minindex)count++;
            }
            for (int i = 0; i < n; i++) {
                if (i != n - 1) Console.Write(A[i] + " ");
                else Console.WriteLine(A[i]);
            }
            Console.WriteLine(count);
        }
    }
