Question

Есть список a = [1, 2, 3, 4, 5, 6]. Требуется удалить из этого списка все нечетные значения, а четные разделить на 2. Всю операции производить с текущим списком, второй список создавать нельзя. Вывести измененный список в консоль.

Answer 1

Ответ:

a = [1, 2, 3, 4, 5, 6, 10]

a = list(filter(lambda x: x % 2 == 0, a))  # Удаляем нечетные

a = list(map(lambda x: x // 2, a))  # Делим пополам четные

print(*a)

Problem Analysis

To solve this problem, we need to iterate through the given list and perform the following operations: 1. Remove all odd values from the list. 2. Divide all even values by 2.

We should perform these operations on the current list itself, without creating a second list. Finally, we need to print the modified list.

Solution

Here is the step-by-step solution to the problem:

1. Start with the given list: `a = [1, 2, 3, 4, 5, 6]`. 2. Iterate through each element in the list. 3. Check if the element is odd or even. - If the element is odd, remove it from the list. - If the element is even, divide it by 2. 4. Print the modified list.

Let's implement this solution in Python:

a = [1, 2, 3, 4, 5, 6]

# Iterate through each element in the list
i = 0
while i < len(a):
    # Check if the element is odd or even
    if a[i] % 2 == 0:
        # Divide even values by 2
        a[i] = a[i] // 2
        i += 1
    else:
        # Remove odd values from the list
        a.pop(i)

# Print the modified list
print(a)

Output

The output of the above code will be: ``` [1, 1, 2, 3] ```

Note: The output may vary depending on the initial list provided.

Explanation

In the given solution, we start with the list `[1, 2, 3, 4, 5, 6]`. We iterate through each element of the list using a while loop and perform the following operations:

1. For the first element, `1`, we remove it from the list since it is odd. The list becomes `[2, 3, 4, 5, 6]`. 2. For the second element, `2`, we divide it by 2, resulting in `1`. The list becomes `[1, 3, 4, 5, 6]`. 3. For the third element, `3`, we remove it from the list since it is odd. The list becomes `[1, 4, 5, 6]`. 4. For the fourth element, `4`, we divide it by 2, resulting in `2`. The list becomes `[1, 2, 5, 6]`. 5. For the fifth element, `5`, we remove it from the list since it is odd. The list becomes `[1, 2, 6]`. 6. For the sixth element, `6`, we divide it by 2, resulting in `3`. The list becomes `[1, 2, 3]`.

Finally, we print the modified list `[1, 1, 2, 3]`.
