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

9

Solution in C (judge verdict: Time Limit Exceeded)

#include <stdio.h>

int main(){
    int n,i,j,l=0,flag,x,y;
    scanf("%d",&n);
    int A[n];
    for(i=0;i<n;i++){
        scanf("%d",&A[i]);
    }
    while(flag==0){
        flag=0;
        l++;
        for(j=0;j>n-1;j--){
            if(A[j]<A[j-1]){
                x=A[j];
                y=A[j-1];
                A[j]=y;
                A[j-1]=x;
                flag=1;
            }
        }
    }
    for(i=0;i<n;i++){
        printf("%d ",A[i]);
    }
    printf("%d\n",l);
    return 0;
}
