Given

Required
Course sequence to satisfy the prerequisite
From the course prerequisite, we have:
and 
This means that LA15 and LA22 are the base courses, and they have no prerequisite. So, we have:
![[LA15; LA22]](https://tex.z-dn.net/?f=%5BLA15%3B%20LA22%5D)
LA16 and LA31 have LA15 as their direct course prerequisite. So, the sequence becomes
![[LA15 \to [LA16, LA31]; LA22]](https://tex.z-dn.net/?f=%5BLA15%20%5Cto%20%5BLA16%2C%20LA31%5D%3B%20LA22%5D)
To complete the sequence, we read each course and place them other their prerequisite.
