I$\text{'}$m trying to determine if my runtime analysis chart is correct.

Project guidelines:

Show how to create course objects, so that one course object holds data from a single line from the input file.

Using this pseudocode written for the previous assignments, analyze the worst$-$case running time of each, reading the file and creating course objects, which will be the Big O value. This should not include the pseudocode written for the menu or the sample schedule above. To do this, do the following:

Specify the cost per line of code and the number of times the line will execute. Assume there are n courses stored in the data structure.

Assume the cost for a line to execute is $1$ unless it is calling a function, in which case the cost will be the running time of that function.

Here is the pseudocode that the chart is based on:

Vector Data Structure Pseudocode:

$//$ Define course object

DEFINE Course:

SET variable courseID to data type String

SET variable courseTitle to data type String

SET variable prerequisites to data type Vector of String

$//$ Function to open file, view data, parse lines, and verify formatting

FUNCTION readFile$($filename$)$

OPEN file using filename

IF file is successfully opened

INITIALIZE vector $$courseDetails$$ for storing course data

INITIALIZE vector $$courseIDs$$

WHILE file lines are open

INITIALIZE String courseData

READ line from file

IF line contains two or more parameters

PARSE line to gather course data

SET courseID to first parameter

ADD courseID to vector $$courseIDs$$

IF line contains prerequisites

DELCARE prerequisites as rest of parameters

FOR each prerequisite in prerequisites

IF prerequisites do not exist in $$courseIDs$$ vector

PRINT $$Error: Prerequisite not found.$$

BREAK

ENDFOR

ENDIF

DELCARE newCourse as Course object with courseID, courseTitle, and prerequisites

ADD newCourse to vector courseDetails

ELSE

PRINT $$Error: Invalid course information.$$

ENDIF

ENDWHILE

CLOSE file

FOR each course ID in vector courseIDs

IF courseID not in vector courseDetails

PRINT $$Error: Course without details: $+$ courseID

ENDIF

ENDFOR

ELSE

PRINT $$Error: Could not open file.$$

ENDIF

END FUNCTION
