Administrative

Assessment

Lab project --> 60 points
Course examination --> 30 points (30%)
Lab activity --> up to 10 points cumulated over the entire 14 weeks

The contents of the tests will be oriented towards verifying the level of understanding of the concepts, results, and way of thinking presented at the course and at the laboratories. Therefore, the answers must be based on these elements, the alternative solutions being considered only if they are correlated/compared with those taught in the course/laboratories or if they are part of the recommended additional bibliography, in which case it must be mentioned.

Minimal performance standards

10 points from the course examination
20 points from lab project

The status of graduated / non-graduated is established only according to the fulfillment of the minimum performance standards (all of them). The total score reflects the fulfillment of the minimum standard only if it incorporates sufficient points in the evaluation of the elements included in the standards.

Grades

They are established according to the distribution of the scores of those promoted: the sum of the scores obtained at the laboratories and the ones from the tests. The percentages proposed by ECTS ("top 10%, next 25%, next 30%, next 25%, lowest 10%") correspond to the normal distribution and are indicative. Their application will be made with possible changes, depending on the actual distribution of scores.

For this reason, the ECTS percentages are only supported as a starting point in establishing the final grades; if the distribution of scores is different than the normal one, the percentages will be adjusted accordingly.

For students from past years

Previous results obtained on past Android courses/labs will NOT be equated. You will need to take both the lab and course tests to pass the mobile programming course.

Conducting the courses and the labs

Both Course and Lab will be held on-site. For asynchronous communication, the discipline's Discord Server will be used.

RO: Reguli alegere proiect:

Proiectele sunt individuale si nu se pot face in echipa.
Proiectele sunt impartite in 3 categorii (A, B, C) in functie de complexitate.
Proiectele trebuie alese pana pe 15.04.2026 si nu mai pot fi schimbate.
Orice proiect poate fi ales de maxim 5 studenti. Proiectele vor fi asignate pe criteriul: primul venit, primul servit.
Alegerea proiectului inseamna trimitirea unui mesaj privat pe Discord catre profesorul de laborator. Mesajul trebuie sa contina numele studentului si id-ului proiectului. Ex: Popescu Marian - proiect A7
Proiectele pot fi prezentate in oricare laborator din a doua partea a semestrului (laboratoarele 9-14).
Proiectele pot fi punctate si partial.
Orice proiect cu mentiunea (mobile + web) trebuie sa aiba implementare specifica pentru ambele platforme. (si nu doar sa va bazati pe faptul ca flutter suporta ambele platforme si ca transforma automat ui-ul pentru a se potrivi pe ambele platforme).
Pentru propunerile personale trebuie sa discutati cu profesorul de laborator pentru a va incadra propunerea in una din cele 3 categorii.

EN: Project Selection Rules:

Projects are individual and cannot be done in teams.
Projects are divided into 3 categories (A, B, C) based on complexity.
Projects must be chosen by April 15, 2026 and cannot be changed afterward.
Any project can be selected by a maximum of 5 students. The projects will be assigned on a first-come, first-served basis.
Choosing the project means sending a private message on Discord to the lab professor. The message must include the student's name and the project ID. Example: Adams Thomas - project A7
Projects can be presented in any lab session during the second half of the semester (labs 9-14).
Projects can also be graded partially.
Any project labeled (mobile + web) must have a specific implementation for both platforms (you cannot rely solely on Flutter’s ability to support both platforms and automatically adjust the UI).
For personal project proposals, you must discuss with the lab professor to classify your proposal into one of the three categories.

Write a dart function that converts a string of characters written in UppeCamelCase into lowercase_with_underscore.

Laborator 02

Problema 1:

Pentru o lista de numere primite ca parametru sa se afiseze sub-lista cu suma maxima.

Exemplu:

Cmd: "maxsumarray.exe -2 1 -3 4 -1 2 1 -5 4"

Output: 6

Explicatie: [4,-1,2,1] are cel mai mare sum = 6.

Problema 2:

Sa se construiasca un Map (dictionar) cu mai multe nivele unde fiecare cheie este o litera dintr-un cuvant iar valorea este fie urmatoarea litera din cuvant daca aceasta exista, fie numarul aparitiilor acelui cuvant. Pentru "abcd" si "adcb" ar arata astfel:

{
    "a": {
        "b": {
            "c": {
                "d": 1
            }
        },
        "d": {
            "c": {
                "b": 1
            }
        }
    }
}

Pentru o linie de comanda precum "freq.exe abcd adfc albc adbc arlv ab" sa se afiseze cate cuvinte incep cu "ab" (ultimul parametru) precum si cuvintele. In caz ca nu se gaseste niciunul se va afisa 0. Pentru exemplu de mai sus s-ar afisa:

Exemplu:

Cmd: "freq.exe abcd adfc albc adbc arlv ab"

Output:

    Count: 1

    abcd

Problema 3:

Pentru doua stringuri a si b, sa se verifice daca a este subsecventa a lui b. Se considera subsecventa a unui string, un nou string care este format din caracterele stringului original stergand unele caractere, fara sa schimbe pozitia caracterelor ramase (ex. "ace" este subsecventa a lui "abcde", dar "aec" nu este)

Problema 4:

Pentru 2 stringuri a si b sa se verifice daca a este anagrama a lui b. O anagrama este un cuvant format din literele altui cuvant, dar in alta ordine.

Lab 02 - Tuesday - 10-12

Problem 1:

For a list of numbers received as a parameter, display the sublist with the maximum sum.

Example:

Cmd: "maxsumarray.exe -2 1 -3 4 -1 2 1 -5 4"

Output: 6

Explanation: [4,-1,2,1] has the highest sum = 6.

Problem 2:

Construct a Map (dictionary) with multiple levels where each key is a letter from a word, and the value is either the next letter in the word if it exists, or the number of occurrences of that word. For "abcd" and "adcb", it would look like this:

{
    "a": {
        "b": {
            "c": {
                "d": 1
            }
        },
        "d": {
            "c": {
                "b": 1
            }
        }
    }
}

For a command line like :

"freq.exe abcd adfc albc adbc arlv ab"

display how many words start with "ab" (the last parameter) as well as the words themselves. If none is found, display 0. For the above example, it would display:

Example:

Cmd: "freq.exe abcd adfc albc adbc arlv ab"

Output:
Count: 1
abcd

Problem 3:

For two strings a and b, verify if a is a subsequence of b. A subsequence of a string is a new string that is formed by deleting some characters of the original string without changing the position of the remaining characters (e.g., "ace" is a subsequence of "abcde", but "aec" is not).

Problem 4:

For 2 strings a and b, check if a is an anagram of b. An anagram is a word formed by rearranging the letters of another word.

Problema 2:

RO: Se da de la tastatura un sir de litere si numere (unde fiecare numar corespunde literei anterioare) si un cuvant. Pentru cuvantul primit sa se afiseze suma numerelor, folosind valoarea corespunzatoare pentru fiecare litera din cuvant.

EN: A sequence of letters and numbers is given from the keyboard (where each number corresponds to the previous letter) along with a word. For the given word, display the sum of the numbers using the corresponding value for each letter in the word.

Exemplu:

Cmd: "wordsum.dart A 5 B 3 C 9 ABBCC"

Output: 29

Problema 3:

RO: Pentru o lista data, sa se returneze numarul de "perechi bune". O pereche (i, j) este buna daca list[i] == list[j] si i != j. Fiecare pereche va fi reprezentata printr-un set.

EN: For a given list, return the number of "good pairs." A pair (i, j) is considered good if list[i] == list[j] and i != j. Each pair will be represented as a set.

Problema 4:

RO: Se da un numar n. Fiecare numar de la 1 la n este grupat in functie de suma cifrelor sale. Sa se returneze numarul de grupuri care au cele mai multe numere.

EN: A number n is given. Each number from 1 to n is grouped based on the sum of its digits. Return the number of groups that contain the most numbers.

Exemplu 1:

Input: n = 13

Output: 4

Explicatie:
RO: Sunt 9 grupuri in total, sunt grupate in functie de suma cifrelor numerelor de la 1 la 13:   
EN: There are 9 groups in total, grouped based on the sum of the digits of the numbers from 1 to 13.

[1,10], [2,11], [3,12], [4,13], [5], [6], [7], [8], [9].

RO: Sunt 4 grupuri ce au cele ai multe numere.
EN: There are 4 groups that have the most numbers.

Problem 1:

Implement a Queue (push(), pop(), back(), front(), isEmpty(), toString()).

Problem 2:

Implement a class with a fromXml() constructor + toXml().

  class Example{
  
      int varA;
  
      int varB;
  
      String varC;
  
      List <int> varD;
  
      double varE;
  
  }

Problem 3:

a) Create a class Client that have 2 private attributes:

Name - can't be changed
PurchasesAmount(double) - that have 2 methods: get(), add()

b) Create a constructor that initialize the name

c) Create a class LoyalClient that have 1 private attribute:

PurchasesAmount(double) - that have 1 method: get() (use different name from the method in superclass)

d) Create a method discount() that assign to PurchasesAmount (subclass) the value of PurchasesAmount (superclass) after reduction of 10%.

e) Create a small test program (main).

The english translation

Problema 1:

Scrieti o functie care primeste ca parametru un String regex, un String text si un int x, si returneaza substringurile de lungime x sau mai mari care fac match pe expresia regulata.

Problema 2:

Implementati o Stiva folosind fisiere ca storage. (pop, push, top)

Problema 3:

Implementati clasa MathOps unde T si G pot fi int, double sau String:

MathOps <T,G> {
    dynamic sub(T obj1, G obj2);
    dynamic mul(T obj1, G obj2);
}

Pentru String implementati sub ca diferenta dintre lungimile celor doua stringuri si mul va arunca exceptie.

Problema 4:

English

Exercise 1:

Write a function that takes as parameters a String regex, a String text, and an int x, and returns the substrings of length x or larger, that match the regular expression.

Exercise 2:

Implement a Stack using files as storage. (pop, push, top)

Exercise 3:

Implement the MathOps class where T and G can be int, double, or String.

MathOps <T,G> {
    int sub(T obj1, G obj2);
    int mul(T obj1, G obj2);
}

In the case of String, sub should return the difference between the lengths of the two strings and mul should throw an exception.
