The feedback on my pseudo code was:

"Your pseudocode handles file reading well, but it should include a check to ensure all prerequisites exist as keys in the hash table."

"The$$Course$$object creation is clear, but you should specify how prerequisites are stored and address potential duplicate$$courseNumber$$keys$."$

"The print function is well$-$designed, but refining the handling of missing prerequisites and improving output formatting would enhance clarity."

Can you please help me adjust the pseudo code to accommodate the feedback?

Pseudocode

$//$ Function to open and parse file, and load courses from file into a hash table

void loadCourses$($Hashtable courses, String fileName$)\{$

OPEN file filename;

WHILE not end of file $\{$

$$ READ line;

$$ SPLIT line by commas into tokens;

$$ IF tokens.length $<2\{$

$$ PRINT "Error: Invalid format";

$$ CONTINUE;

$\}$

$$ courseNumber $=$ tokens$[0]$;

$$ prerequisites $=$ tokens$[2$ to end$]$;

$$ CREATE new Course object with courseNumber, name, and prerequisites;

$$ ADD Course object to hash table with key $=$ courseNumber;

$\}$

CLOSE file

$\}$

$$

$//$ Function to print course information and prerequisites

void printCourseInformation$($Hashtable courses, String courseNumber$)\{$

IF course does not contain key courseNumber $\{$

$$ PRINT "Course not found";

For each prerequisite in course.prerequisites:

IF courses contains key prerequisite $\{$

$$ prereqCourse $=$ courses$[$prerequisite$]$;

$$ PRINT $"-"+$ prereqCourse.courseNumber $+"$: $"+$ prereqCourse.name;

$$ELSE $\{$

$$ PRINT $"-$ Missing prerequisite: $"+$ prerequisite;
