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: Runtime Error)


using System;


	public class Bubble
	{
		public static void Main(string[] args)
		{
			int count=int.Parse(Console.ReadLine());			
			string data=Console.ReadLine();
			string[] num=data.Split();
			int[] target=new int[count];
			int temp;
			int sortCount=0;
			for(int d=0;d<num.Length;d++)
			{
				target[d]=int.Parse(num[d]);
			}
			
			for(int i=0;i<count-1;i++)
			{
				for(int j=count-i;j>i;j--)
				{
					if(target[j]>target[j-1])
					{
						temp=target[j-1];
						target[j-1]=target[j];
						target[j]=temp;
						sortCount++;
					}
				}				
			}
			Console.Write(target[0]);
			for(int k=1;k<target.Length;k++)
			{
				Console.Write(" "+target[k]);
			}
			Console.Write("\r\n");
			Console.WriteLine(sortCount);
		}
