# Data Structures I — The Rules of the Game

## Course structure

There are **lectures** and **recitations** (practicals).

To pass the course, you need to pass an **exam** (written/oral,
covers theory) and get **class credit** from the recitations.

## Requisite knowledge

- Programming
- Basic algorithms and data structures: e.g., balanced search trees (AVL/red-black/…)
- Discrete math (combinatorics, basic number theory)
- Basic probability theory (linearity of expectation, …)

If you are missing any of these, please ask for help **soon.**

## Assignments

Overview:

- There are at least 8 programming assignments per 10 points
- and at least 4 experimental assignments per 15 points
**You need 90 points for class credit**- Deadline: 2 weeks (longer at the end of semester)

Programming assignments:

- You are given a partial implementation of a DS
- Implement the missing bits
- Automatic checking, tests are public
- Instructor looks at the source code
- C++ and (usually) Python available

Experimental assignments:

- Measure properties of a given implementation
- Write a report (and submit PDF)

## General rules

- Feel free to talk about assignments with other people,
but
**do not share code nor reports**(except with the instructor). - Do not share
**example solutions**with anybody. **Deadlines**are strict.- Before deadline, you can
**re-submit.** - The code must pass
**all tests.** **Quality**of your code and reports contributes to grading.- Do not use non-trivial
**code you didn't write**yourself. This includes other peoples' implementations and non-obvious library functions. Trivial cases of growing arrays (appending to`std::vector`

in C++ or`list.append()`

in Python) are permitted, anything more complicated isn't. When in doubt, ask your instructor. - All theorems used in your reports must be stated in full and their source
must be
**properly cited**. If the theorem was stated at the lecture, citing the lecture is considered sufficient.
