There are 10 birds sitting on a wire in queue. A hunter has 3 bullets in his rifle. Each time he shoots a bird, the adjacent bird(s) next to it flies away.

In how many orders the hunter can shoot three birds?

**Details and Assumptions:**

The hunter shoots exactly 3 times.

You can assume that he doesn't miss.

Shooting orders means the pattern he is shooting three birds. For example, counting from the left he can shoot the 5th bird first, then 1st bird & then maybe 10th bird. That's one of the orders.
