Teaching Schoolchildren to Solve Problems on the Topic "Working with Bits"

The author has taught programming to schoolchildren of different ages for many years. All this time, the author has been creating literature for independent study by schoolchildren, trying to present the material in the simplest, most visual, and understandable form possible. This article provides an example of such material for teaching problem-solving in computer science on the topic "Working with bits". Such material may be of interest to teachers both as an illustration of the teaching methodology and in terms of content. At the same time, the author believes that this material may be very useful and interesting for schoolchildren engaged in self-study. All interested parties are offered the following work order: put the article aside and try to independently complete the proposed task the first time - after reading the problem statement, the second time - after reading the instructions for the solution.
