## Question

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:

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
