I think summer is the best season of all because it is warm, the nature is beautiful and we have great opportunities for rest. Summer is a time of holidays. We can go anywhere, spend our time near a river or a lake on fresh, green grass, swim in warm water, or climb mountains, play different games, ride a bicycle and so on.I spend my summer holidays at my granny’s. There are many things there to do. What I did most of the time - I swam in the sea and sunbathed. Sometimes I made a fire with my friends at the seaside and cooked potatoes there. It was wonderful. We told anecdotes to each other, and did everything we wanted. I also got used to walk alone in the forest.When August was coming to its end, I went on a small voyage by ship. The ship name was “Sevastopol”.But this summer wasn’t for me only sugar and honey. I have passed through the graduating exams after school and entering exams in the university. So the bigger part of my summer vacations I spent sitting with the books. Of course, it was not interesting, but I’m glad that I did it because now I’m a student of the best university in our country.
суммы отнимаем эти 5 и делим на два, получаем (25-5)/2=10. Значит число которое мы ищем находиться на расстоянии 10 от 5 влево или от 20 вправо. Для определения в какую сторону нужно сместить любое из названных чисел на 1, то есть берем 14 и 20. В ответ получаем сумму 9+15=14. Так как сумма меньше то нужно двигаться именно в этом направлении. Теперь можем от 15 отнять 10 и получить 5. Если бы число было вправо от 20, то сумма увеличилась бы, и тогда мы точно знали что это 30. Так что ответ будет за два хода.
