Maze wall hugging both clockwise and anti-clockwise

Question

So I did the algorithm for the vehicle to go in a clockwise direction(Refer to my pseudocodes below). But now that my school had said there will be an anti-clockwise direction as well, I'm not sure what to do. Do I only reverse the logic of my pseudocode below? Do I use switch cases as well? I'm not sure. So the vehicle must be able to move both clockwise and anti-clockwise around the 'maze'

/* Check if the left sensor is blocked*/
if(left sensor ==true )
{
    if(Obstacle detected)
    {
        move_forward;
    }
}
/* Check if the back-left sensor is blocked*/
if(back-left sensor ==true)
{
    if(Obstacle detected)
    {
        move_diagonal_front_left;
    }
}

/* Check if the front-left sensor is blocked*/
if(front-left sensor== true )
{
    if(Obstacle detected)
    {
        move_diagonal_front_right;
    }

}

/* Check if the front sensor is blocked*/
if(front sensor== true )
{
    if(Obstacle detected)
    {
        move_right;
    }

}

/* Check if the front-right sensor is blocked*/
if(front-right sensor== true )
{
    if(Obstacle detected)
    {
        move_diagonal_back_right;
    }

}

/* Check if the right sensor is blocked*/
if(right sensor== true )
{
    if(Obstacle detected)
    {
        move_back;
    }
}

/* Check if the back-right sensor is blocked*/
if(back-right sensor== true )
{
    if(Obstacle detected)
    {
        move_diagonal_back_left;
    }
    else if(Obstacle cleared)
    {
        Move_backwards;
    }
}
