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

Sample Input 1

5
5 3 2 4 1

Sample Output 1

1 2 3 4 5
8

Sample Input 2

6
5 2 4 6 1 3

Sample Output 2

1 2 3 4 5 6
9

Solution in C# (judge verdict: WA: Presentation Error)

using System;

class Bubble_Sort
{
    public static void Main()
    {
        int n = int.Parse(Console.ReadLine());
        string str_num = Console.ReadLine();
        string[] tmp_num = str_num.Split(' ');
        bool flag = true;
        int cnt=0;

        int[] numbers = new int[2];
        Array.Resize(ref numbers,n);

        for(int i=0;i<n;i++)
        {
            numbers[i] = int.Parse(tmp_num[i]);
        }

        while(flag)
        {
            flag = false;

            for (int i = 0; i < n - 1; i++)
            {
                if(numbers[i]>numbers[i+1])
                {
                    int tmp = numbers[i + 1];
                    numbers[i + 1] = numbers[i];
                    numbers[i] = tmp;
                    flag = true;
                    cnt++;
                }
            }
        }
        
        for(int i=0;i<n;i++)
        {
            Console.Write("{0} ",numbers[i]);
        }

        Console.WriteLine();
        Console.WriteLine(cnt);
    }
}
