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: Time Limit Exceeded)

#include<stdio.h>
int main(){
  int A[100];
  int  N;
  int i,j,flag=0;
  scanf("%d",&N);
  for(i=0;i<N;i++){
    scanf("%d",&A[i]);
  }
  while(flag<N){
    if(A[j]<A[j-1]){
	A[j]=A[j-1];
	flag++;
    }
printf("%d ",A[j]);
    
  }
  printf("\n");
  printf("%d\n",flag);
  return 0;
}
