Answer 1

Сравниваешь уровень яда в любом яблоке и в другом, находящемся через 2 яблока

Таким образом, как минимум 1 яблоко будет нормальным

Если прибор говорит о равном уровне яда, то оба проверяемых яблока съедобны

Если прибор говорит о том, что в каком-то яблоке больше яда, то тогда можно будет взять здоровое яблоко и соседнее с ним, находящееся дальше от ядовитого

Всё, 2 яблока за 1 измерение найдены

Finding Two Good Apples Using the Magic Device

To find two good apples among the seven apples, you can use the magic device that compares the level of poison in two apples. Here's a step-by-step guide:

1. Divide the apples into three groups: Group A, Group B, and Group C. Group A will contain the first three apples, Group B will contain the next three apples, and Group C will contain the last apple.

2. Compare the poison levels: - Compare the poison level of the first apple in Group A with the first apple in Group B using the magic device. - If the magic device indicates that the first apple in Group A has a higher poison level, then it means that one of the first three apples is poisonous. In this case, move to Step 3. - If the magic device indicates that the first apple in Group B has a higher poison level, then it means that one of the next three apples is poisonous. In this case, move to Step 4. - If the magic device indicates that the poison levels are the same, then it means that the last apple in Group C is poisonous. In this case, move to Step 5.

3. Identify the poisonous apple among the first three apples: - Now that you know one of the first three apples is poisonous, you can use a similar process to identify the specific apple. - Divide the first three apples into two groups: Group A1 and Group A2. - Compare the poison levels of the first apple in Group A1 with the first apple in Group A2 using the magic device. - If the magic device indicates that the first apple in Group A1 has a higher poison level, then it means that the first apple in Group A1 is poisonous. Otherwise, the second apple in Group A1 is poisonous.

4. Identify the poisonous apple among the next three apples: - Now that you know one of the next three apples is poisonous, you can use a similar process to identify the specific apple. - Divide the next three apples into two groups: Group B1 and Group B2. - Compare the poison levels of the first apple in Group B1 with the first apple in Group B2 using the magic device. - If the magic device indicates that the first apple in Group B1 has a higher poison level, then it means that the first apple in Group B1 is poisonous. Otherwise, the second apple in Group B1 is poisonous.

5. Identify the poisonous apple among the last apple: - Since the magic device indicated that the last apple in Group C has the same poison level as the other apples, it means that the last apple is also poisonous.

By following this process, you can identify the two good apples among the seven apples using the magic device.
