So how it is going like this? so which is in clockwise direction, okay? clockwise direction, but the fourth which one is fourth priority group is in horizontal line.
01:24
That's why we reverse the configuration.
01:27
So it's why it is our configuration.
01:30
So we will reverse due to the presence of fourth priority group in on horizontal line.
01:35
So this one is, it's why it is, it is a configuration.
01:36
So it's why it's why it is, it is, our configuration.
01:36
So we will reverse due to the presence of the yes form.
