babb | bad_alloc Behaving Badly

I have a db structured like this:

Could you please help me? I need to write code for a one-tape Turing Machine that uses the following two-letter alphabet a and b.
So the programme should show the common prefix of the two words.
For example:
g(aab,aaaba) -> aa; g(_,abab) -> _; g(aaba,baa) -> _; g(_,_) -> _; g(babaab,babb) -> bab
Where g is the function of the Machine and underscore means an Empty word, between words we have space
I tried to implement the following option:
If at the start we see the letter a, then we erase it and move to the beginning of the second word. If we also see a letter a there, we erase it too and after both words we write a through a space. After that we return to the beginning of the first word and repeat this operation. When the first letter of the first word and the first letter of the second no longer match, we erase everything that is left. But I have some troubles with code, because after each operation a space between two words gets longer and I don't know how to control this. Also there is a trouble when the first or the second word is a common prefix fully, like this:
g(baa,baabab) -> baa

I have a function called four_letter_list and the goal is to return a new list that has randomized 4-letter words that can be constructed using the "nth" letter of the alphabet

You cannot use built in python functions besides len, range, for loops, while loops and if-elif-else statements.

ex: def four_letter_words(2) returns the list ['AAAA', 'AAAB', 'AABA', 'AABB', 'ABAA', 'ABAB', 'ABBA', 'ABBB', 'BAAA', 'BAAB', 'BABA', 'BABB', 'BBAA', 'BBAB', 'BBBA', 'BBBB']

This is the code I have

I have been trying to figure out how to use the beta notifications resource to send push notifications to users in Teams, but I cannot get past step 1.

User signs in to your application, which creates a subscription with the Microsoft Graph notification service.

I am not using a language with Microsoft library support so I cannot use their SDKs. Instead, I am manually sending http requests. I have tried many, but I can't even nail down what the "resource" is supposed to be in the subscription type. Here are some of the things I have tried and the results:

Sending this message:

Let me start by saying I failed this challenge - it's already over, I didn't complete it, didn't get the job - so, don't tell me I am cheating by asking for help. I had 90 minutes to solve this.

BTW, if someone knows what this general class of problem is referred to as, please let me know.

Here is, as close as I can remember, the question.

Given a random sequence of characters from the set {'a', 'b'}. Create 3 subsets from the sequence, example: given aaaa the subsets are:

1. a-a-aa
2. a-aa-a
3. aa-a-a

Each subset must have at least 1 'a' If the sequence has zero 'a' , then list the possible groups of b (as above with 4 'a') If the sequence has only 1 or 2 'a', then do not process (this is of course, trivial to test)

so, here is a slightly more advanced example:

Given "babbaaba"

The subsets would be:

1. ba-bbaab-a
2. bab-baab-a
3. babb-aab-a
4. babba-ab-a
5. ba-bbaa-ba
6. ba-bba-aba
7. bab-baa-ba
8. bab-ba-aba etc... (sorry, incomplete, don't need to bore you)

I cannot figure out a good way to solve this, I have looked at my (manual) process, over and over, and don't really see any algorithm emerging from it.

There was a limit to the maximum set size, perhaps 10,000 characters. Presumably to indicate that use of recursion won't be a problem.

I wrote a SQL command which inserts multiple rows. The formattable string that generates here, executes successfully if copy/paste it to SSMS and run, but inside the ExecuteSqlCommand method it throws an exception:

An exception of type 'System.Data.SqlClient.SqlException' occurred in App.Api.dll but was not handled in user code. Incorrect syntax near '@p0'

which typically tells that something is wrong with a script, but it's not that case. Maybe somebody knows what is the problem?

I'm working on remove left recursion in grammar. (3 grammars)
