How do I write pseudocode where input is a table and output is a list for this example: Please see the table attached. It's a table where the first column are students in a classroom and they are ranked based on their performance from the exams. A. I want to write a pseudocode algorithm to determine the rank changes after the exam. Input is the table with n rows, and 5 columns. So far I have this: M[n-1,4] The output should be a list with the differences in ranks for each student. For example [2,3, -4, 0, -7] B How do I write a pseudocode algorithm to determine which student scored at least 90% of the questions they completed. Output should produce a list eg.[0,4] Thanks for your help.
