Strategy of guessing exercises – Variations of drawing trees
Viktória Bakonyi, László Zsakó · 2015
In informatics we often have to tempt students to solve different problems.This is required partly during practice and partly during tests (moreover this is especially important in the preparation for informatics competitions).We give two different methods of creating different but still commensurate exercises: one of them is to start from a base problem, and make some changes on it in small steps; the other way is to look for variations of the base task solution.1 [11]
