Answer:

LA15; LA22

LA16; LA31; LA32

LA169; LA126;

LA127; LA141

Explanation:

Given

$Courses: LA15,\ LA16,\ LA22,\ LA31,\ LA32,\ LA126,\ LA127,\ LA141,\ LA 169.$

Required

Course sequence to satisfy the prerequisite

From the course prerequisite, we have:

$1.\ LA15 \to None$ and $3.\ LA22 \to None$

This means that LA15 and LA22 are the base courses, and they have no prerequisite. So, we have:

$[LA15; LA22]$

LA16 and LA31 have LA15 as their direct course prerequisite. So, the sequence becomes

$[LA15 \to [LA16, LA31]; LA22]$

To complete the sequence, we read each course and place them other their prerequisite.

<em>See attachment for complete tree</em>

<em></em>

From the tree, we have the sequence to be:

<em>LA15; LA22</em>

<em>LA16; LA31; LA32</em>

<em>LA169; LA126;</em>

<em>LA127; LA141</em>
