Answer:
Singleton pattern is the pattern for design that is build using the global variables which creates a lot of drawback in the designing. Singleton pattern are considered with the global variable and thus cannot be bound into single unit which complexes the components in design.
They have a loose coupled variables in design and also does not show the property of the multi-threading .These feature are responsible for the decrement in the performance and thus are not highly preferred choice for the pattern.So, it is known as the "anti- pattern".
Answer:
LA15; LA22
LA16; LA31; LA32
LA169; LA126;
LA127; LA141
Explanation:
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.

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>
