QUESTION
I've got a list of strings, for example: ['Lion','Rabbit','Sea Otter','Monkey','Eagle','Rat']
I'm trying to find out the total number of possible combinations of these items, where item order matters, and the total string length, when all strings are concatenated with comma separators is less than a given length.
So, for max total string length 14, I would need to count combinations such as (not exhaustive list):
- Lion
- Rabbit
- Eagle,Lion
- Lion,Eagle
- Lion,Eagle,Rat
- Eagle,Lion,Rat
- Sea Otter,Lion
- etc...
but it would not include combinations where the total string length is more than the 14 character limit, such as Sea Otter,Monkey
I know for this pretty limited sample it wouldn't be that hard to manually calculate or determine with a few nested loops, but the actual use case will be a list of a couple hundred strings and a much longer character limit, meaning the number of nested iterations to write manually would be extremely confusing...
I tried to work through writing this via Python's itertools, but keep getting lost as none of the examples I'm finding come close enough to what I'm needing, especially with the limited character length (not limited number of items) and the need to allow repeated combinations in different orders.
Any help getting started would be great.

This is my main.dart file:
...ANSWER
Answered 2021-Jun-05 at 20:09You need to let dart know the type of questions[_questionIndex]['questionText']
Try this:
Change questions[_questionIndex]['questionText']

QUESTION
I have a list of dictionaries with questions. Need to loop over the dictionaries one at a time, can be done randomly as well. Each question has 2 parts and need to go through them separately.
For example: question - 'Am I dog?'
if the user answers 'yes'
, they should get 'bark'
, if they answer 'no'
, they should get 'what am I?'
.
The code is as follows:

Answered 2021-Jun-02 at 00:05This should work. i is a dictionary itself so I did a key look-up with i.

This node at the center of your diagram
is pointing to three other nodes. So it cannot be represented correctly by your node class.
You have a big problem!
