Course detail

Algorithms and Data Structures

FEKT-BPC-ALDAcad. year: 2020/2021

The first part of the course is focused on introducing students to the basic concepts: algorithm, time and memory complexity of the algorithm, data container / collection.
The second part of the course deals with the concepts: abstract data type: (Vector, Stack, Queue, Set, Tree) and the use of iterators for these data types.
In the third part, students will learn about recursive and non-recursive algorithms, sorting and searching algorithms.

Learning outcomes of the course unit

The student is able:
- analyze the task using a flowchart;
- to determine its time and memory complexity for a simple algorithm;
- use basic abstract data types (Vector, Stack, Queue, Set, Tree) and use iterators for these data types.
- solve the problem using recursive and non-recursive algorithms;
- design and implement basic sorting and searching algorithms;
- correctly determine the data type for a given type of calculation (basic data types, pointer type to data type, and composite data type);
- work with dynamically allocated memory (acquisition and release of memory, manipulation of data in allocated memory);
- work with standard inputs, outputs and files;

Prerequisites

Attending BPC-UDP course or similar.

Planned learning activities and teaching methods

Techning methods include lectures and computer laboratory lectures. Students have to create assignments during the computer laboratory lectures.

Assesment methods and criteria linked to learning outcomes

Up to 40 points for the laboratory lectures (2 tests, up to 20 points each). Minimal needed points from laboratory lectures is 15.
Up to 60 points for the final examination. Minimal needed points from final examination is 20.
The course exam will take place in person.
