A python program that helps you create a contest , a list remembering the grade and the number of a student. This is a mandatory homework which had to be done in 3 weeks (my first ever homework from the university).

This is the statement (more info at http://www.cs.ubbcluj.ro/~arthur/Fundamentals%20of%20Programming/Laboratory/Laboratory.02-04.pdf) :

During a programming contest for students, each contestant had to solve 3 problems (named P1, P2 and P3). Afterwards, an evaluation committee graded the solution to each of the problems solved by the contestants using integers between 0 and 10. The committee needs a program that will allow managing the list of scores and establishing the winners. Write a program that will implement the following functionalities (each functionality is exemplified):

1.Add the result of a new participant.

add

insert at

e.g. add 3 8 10 – add a new participant with scores 3,8 and 10 (scores for P1, P2, P3 respectively). insert 10 10 9 at 5 – insert scores 10,10 and 9 at position 5 in the list (positions are numbered from 0).

2.Modify the scores from the list.

remove

remove to

replace <P1 | P2 | P3> with

e.g. remove 1 – set the scores of the participant at position 1 to 0. remove 1 to 3 – set the scores of participants at positions 1,2, and 3 to 0. replace 4 P2 with 5 – replace the score obtained by participant 4 at P2 with 5.

3.Write the participants whose score has different properties.

list

list sorted

list [ < | = | > ]

e.g. list – write the list of participants and their scores for each problem. list < 40 – write the participants having an average score < 40. list = 67 – write the participants having an average score = 67. list sorted – write the participants sorted in decreasing order of their average score.

4.Obtain different characteristics of participants.

avg to

min to

e.g. avg 1 to 5 – writes the average of the average scores for participants between positions 1 and 5 in the list. min 2 to 7 - writes the lowest average score of the participants between positions 2 and 7 in the list.

5.Establish the podium.

top

top <P1 | P2 | P3>

remove [ < | = | > ]

e.g. top 3 – write the 3 participants having the highest average score, in descending order of their average score. top 4 P3 – write the 4 participants who obtained the highest score for problem P3, sorted descending by that score. remove < 70 –set the scores of participants having an average score < 70 to 0. remove > 89 –set the scores of participants having an average score > 89 to 0.

6.Undo the last operation that modified program data.

undo – the last operation that has modified program data will be reversed. The user has to be able to undo all operations performed since program start by repeatedly calling this function.
