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 JAVA (judge verdict: Accepted)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {
	public static void main(String[] args) throws NumberFormatException,
			IOException {
		BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
		byte arrayLength = Byte.parseByte(in.readLine());
		byte[] array = new byte[arrayLength];
		short count = 0;
		String[] strData = in.readLine().split(" ");
		for (byte i = 0; i < arrayLength; i++) {
			array[i] = Byte.parseByte(strData[i]);
		}
		for (int x = 0; x < arrayLength; x++) {
			for (byte y = (byte) (arrayLength - 1); y > x; y--) {
				if (array[y] < array[y - 1]) {
					byte temp = array[y];
					array[y] = array[y - 1];
					array[y - 1] = temp;
					count++;
				}
			}
		}
		for (int z = 0; z < arrayLength; z++) {
			if (z == arrayLength - 1) {
				System.out.println(array[z]);
			} else {
				System.out.print(array[z] + " ");
			}
		}
		System.out.println(count);
