Neskuchny computer science. Theory in stories, tasks, tests, life hacks

The initial meaning of the word “computer science” (invented, by the way, long before computers) is the science of effective work with information. It is this computer science that the book is devoted to. This is a collection of materials for developing an information culture - the ability to work consciously, quickly and efficiently: find the necessary data, structure it, choose a form of representations and tools for work.
In each chapter - a little boring and very practical theory, tasks, exercises, tests. There is no clear binding to the school curriculum, the book is much wider than the discipline.
The book is addressed to adolescents 12-15 years old, but it will be interesting to their parents-you can read in turn, decide together or compete. Level - from the initial to the Olympiad. Some tasks are carried out on a computer (an electronic archive of working materials is available), others will need paper and a pen, others are just a reason to think or experiment.
Do not believe that the theory can be boring, and the exercises are funny? And you will open the book at random
