QUESTION
I'm trying to create an algorithm that will return all the possible combinations from a list of elements (fruits in this example). The challenge is that the elements can be grouped in different sizes and the number of elements on the result list must be equal to n, where n is the list size. In short, all the elements must be on the final list.
Here is an example:
fruits = ['Apple', 'Orange', 'Banana', 'Watermelon']
We can quickly find all the combinations without repetition from size 0 to n as follows:

QUESTION
This is part of my doubly linked list deque python code.
The 'appendleft' function written almost similar to the 'append' function is normally output. Why is the last 'append('apple')' code not output normally in the 'Group_of_append' function?
...ANSWER
Answered 2022-Mar-28 at 12:28Your appends work fine. Problem lies in your print_list function which stops when p.next is None. Which means your last element will not be printed because its next is None.
All in all, your logic for this list is very strange and could use a lot of rework, it would make finding mistakes like this one a lot easier for you. For example, this iterating through the whole list when appending even though you have both head and tail readily available in the deque object.

QUESTION
I want to remove the elements of an array with n elements using a for loop and the splice method one by one. The loop is executed n - 2 times and there will be 2 elements inside the array at the end. Why is that so?
...ANSWER
Answered 2021-Dec-21 at 07:52When you do fruits.splice you are modifying the array used for the for loop itself. If you look at index, it is incrementing in each loop. After Execution Number: 1, it increments to 2 and looks at fruits and sees there is no more elements. Seeing that, it exits the for loop.
If you want to do it with a for loop, what you probably wanted was
