冒泡排序两种方法(从头到尾 和从尾到头扫描 )

int bubbleSort1(int* array,int len )
{
    int i ,j,temp;
    i = j  = temp = 0;
    for(  i = 0;  i < len - 1;i++ )

        for(j = len -1 ;j > i;j-- )
        {
            if( array[j-1] > array[j] )
            {
                temp = array[j-1];
                array[j-1] = array[j];
                array[j] = temp;
            }
        }
    }
    return 0;
}

int bubbleSort2(int* array,int len )
{
    int i ,j,temp;
    i = j  = temp = 0;
    for( i = 0 ; i < len - 1; i++ )
    {
        for( j = 0; j < len - i -1;j++ )

            if( array[j+1] < array[j] )
            {
                temp = array[j+1];
                array[j+1] = array[j];
                array[j] = temp;
            }
        }
    }

    return 0;
}

int main(int argc, char* argv[])

    int i = 0;
    int a[]={1,43,2,5,10,99,35,34,65,3,7,37,25,89,99};
