625_D. Finals in arithmetic
Vitya is studying in the third grade. During the last math lesson all the pupils wrote on arithmetic quiz. Vitya is a clever boy, so he managed to finish all the tasks pretty fast and Oksana Fillipovna gave him a new one, that is much harder. Let's denote a flip operation of an integer as follows: number is considered...
