Problem:
Bubble Sort

Write a program of the Bubble Sort algorithm which sorts a sequence A in ascending order. The algorithm should be based on the following pseudocode:

BubbleSort(A)
1 for i = 0 to A.length-1
2 for j = A.length-1 downto i+1
3 if A[j] < A[j-1]
4 swap A[j] and A[j-1]

Note that, indices for array elements are based on 0-origin.

Your program should also print the number of swap operations defined in line 4 of the pseudocode.

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 spaces 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: Wrong Answer)

using System;

class Program
{
    static void Main()
    {
        int N = int.Parse(Console.ReadLine());
        string[] s = Console.ReadLine().Split();
        int[] A = new int[N];
        for(int k = 0;k < N; k++)
        {
            A[k] = int.Parse(s[k]);
        }

        int swapcounter = 0;
        bool swapped = true;
        int i = 0;
        while (swapped)
        { 
            swapped = false;
            for (int j = A.Length - 1; j > i; j--)
            {
                if(A[j - 1] > A[j])
                {
                    int tmp = A[j - 1];
                    A[j - 1] = A[j];
                    A[j] = tmp;
                    swapped = true;
                    swapcounter++;
                }
            }
        }

        foreach (int x in A)
        {
            if (x == A[A.Length - 1])
            {
                Console.WriteLine("{0}", x);
            }
            else
                Console.Write("{0} ", x);
        }
        Console.WriteLine(swapcounter);
    }
}
