The problem provides pseudocode that assigns grades based on an average mark. The goal is to determine the grade for a given average.

1. Problem Description

The problem provides pseudocode that assigns grades based on an average mark. The goal is to determine the grade for a given average.

2. Solution Steps

The pseudocode uses a series of nested if-else statements to assign grades. Let's analyze the conditions:

* If $average >= 75$, then $result = "A"$

* Else, if $average >= 65$, then $result = "B"$

* Else, if $average >= 50$, then $result = "C"$

* Else, if $average > 35$, then $result = "S"$

* Else, $result = "W"$

To illustrate with some examples:

* If $average = 80$, the condition $average >= 75$ is true, so $result = "A"$.

* If $average = 70$, the condition $average >= 75$ is false. Then the condition $average >= 65$ is true, so $result = "B"$.

* If $average = 40$, the condition $average >= 75$ is false. The condition $average >= 65$ is false. The condition $average >= 50$ is false. The condition $average > 35$ is true, so $result = "S"$.

* If $average = 30$, the condition $average >= 75$ is false. The condition $average >= 65$ is false. The condition $average >= 50$ is false. The condition $average > 35$ is false, so $result = "W"$.

3. Final Answer

The pseudocode assigns grades based on the average: "A" for averages 75 and above, "B" for averages 65-74, "C" for averages 50-64, "S" for averages 36-49, and "W" for averages 35 and below.
