Computer Olympiad Talent Search Solutions
1. Dancing Doll:
A dress-maker had to make dresses for four dolls. Each dress must be made from four different materials.
Question:
Which doll is wearing a dress that is NOT made of four different materials? Click on the correct answer.
Explanation
The correct option is:
The dress-maker has made dresses for the other dolls using all four materials, while with the doll above the rules are not met.
Background information:
Data structures mean storing and manipulating data in the memory of a computer, in a way that the data can be used for constructing rules. This data can take the form of images, numbers or text.
In our example, the four materials that are required to be used are stored in the memory and each image is validated against the rules. The patterns of the images can be interpreted as colours as well. The patterns can be seen physically or calculated mathematically
2. Forest Observation:
Forest rangers need to observe the types of animals that wander onto paths in a forest. They watch the paths from tall observation towers. A ranger can only see the paths that connect directly to their tower.
Question:
Click on the correct and least number of towers that need a forest ranger to observe all the paths. Click on the observation towers that at least need to have a forest ranger to observe all the paths. Click on ‘Save” when you are done.
Explanation:
The correct answer is 3. The three occupied observation towers and the respective overseen paths are shown in the image
There are 8 paths. If only two observation towers were occupied, each one would have to observe at least 4 paths. This is not possible, because no observation tower is next to 4 paths.
Background information:
In Informatics many things can be represented with graphs. Graphs consist of nodes (= circles) and edges (= lines), which connect the nodes. For our example a graph looks like this:
You can ask: “Which nodes (= observation towers) do you have to choose at least such that every edge (= forest path) is next to a chosen node (= observation tower)?” This question is also known as minimal vertex cover. It can for example be applied when putting up street lights, which should illuminate all streets. Another example is cameras, which should cover all hallways.

About Talent Search:
The Computer Talent Search is the South African version of the Bebras Contest which attracts more than two million participants from more than 50 countries in the rest of the world each year. The contest requires the use of Computational Thinking – those skills that are also required for Mathematics, Science, IT and Computer Applications. The Talent Search identifies learners with the skills, but at the same time gives all an opportunity to develop these skills.
The Talent Search is an online test, but for those schools with inadequate connectivity a pen-and-paper version is available which does not require computers. After the Talent Search, learners who have already mastered a computer language can enter the Programming Olympiad. Those who know how to use applications like spreadsheets, databases and a wordprocessor can enter the Applications Olympiad.
