QUESTION
I'm trying to write a regular expression that needs to return every tag name, attribute name, and attribute value
Here is the code example
...ANSWER
Answered 2022-Feb-10 at 06:05I modified your regex to catch the tag name and used named capture groups.
/\[?(?\w+)\s?(?\S+)=['"]?(?(?:.(?!["']?\s+(?:\S+)=|[>"']))+.)["']/gm
This might work for you.

My code is very simple; I have an outlet to a UIButton, button, and I am setting its image in code:
ANSWER
Answered 2021-Oct-04 at 17:26Is this a change in iOS 15?
Yes and no. There is indeed a change in iOS 15, but the reason for the problem you're experiencing is a change in Xcode 13.
The change in iOS 15 is that there's a whole new way of configuring a button. This starts with giving the button one of four new iOS 15 types: Plain, Gray, Tinted, and Filled. If you set your button to have any of those types, you are opting in to the new behavior.
The problem you're seeing is because, in Xcode 13, when you make a button in the storyboard, it does give the button one of those types: Plain. So you have opted into the new dispensation without knowing it!
The solution, if you want the old behavior, is to change the Style pop-up menu (in the Attributes inspector) from Plain to Default. Now you have an old-style button and it will behave in the way you're accustomed to.
(Of course, in the long run, you're going to want to adopt the new dispensation. I'm just explaining the apparent change in behavior.)
QUESTION
Assume we have two tables (think as in SQL tables), where the primary key in one of them is the foreign key in the other. I'm supposed to write a simple algorithm that would imitate the joining of these two tables. I thought about iterating over each element in the primary key column in the first table, having a second loop where it checks if the foreign key matches, then store it in an external array or list. However, this would take O(N*M) and I need to find something better. There is a hint in the textbook that it involves hashing, however, I'm not sure how hashing could be implemented here or how it would make it better?
Editing to add an example:
...ANSWER
Answered 2021-Dec-24 at 22:18Read the child table's primary and foreign keys into a map where the keys are the foreign keys and the values are the primary keys. Keep in mind that one foreign key can map to multiple primary keys if this is a one to many relationship.
Now iterate over the primary keys of the mother table and for each primary key check whether it exists in the map. If so, you add a tuple of the primary keys of the rows that have a relation to the array (or however you want to save it).
The time complexity is O(n + m). Iterate over the rows of each table once. Since the lookup in the map is constant, we don't need to add it.
Space complexity is O(m) where m is the number of rows in the child table. This is some additional space you use in comparison to the naive solution to improve the time complexity.

QUESTION
I tried stopping the column overflow with max-height, max-width, but it doesn't seem to work.
I've made three columns with CSS Grid. One for the nav section, one for the left column and one for the right column. the left column section keeps overflowing over the nav section and the right column section as shown in the screenshots.
What I'm trying to achieve:
What happens:
...ANSWER
Answered 2021-Dec-18 at 21:12To avoid overflowing, you can use the rule white-space: nowrap; for your h1.
However, that will avoid breaking the line after "Hello," as well.
So I would also recommend adding a Hello, for explicitly breaking that line.
That should solve your line-break issues, but I noticed you're also rotating the text by 90deg, and that can mess up the heading fitting inside the cell.
So I recommend adding the rule writing-mode: tb-rl (link) to make the text be written vertically, and then rotating it 180deg instead of 90 (so it becomes bottom-up instead of top-down)
This is your snippet with the suggested changes

I am trying to setup a SwiftUI .contextMenu with a button that toggle a Bool value. The context menu's button text is supposed to change when the Bool toggles. But the context menu doesn't update. Is there a way to force update the context menu?

I have the following dataframes (df11 and df22) I'd like to do a merge/full join on with "UserID=UserID" and date difference <= 30 . So if the UserIDs match up AND the date's are less than or equal to 30, I'd like them merged into one singular row. I've looked at fuzzy join here and sqldf here but I can't figure out how to implement either of those for my data frames.

Answered 2021-Nov-05 at 17:59One way is to first create "+/- 30 day" columns in one of them, then do a standard date-range join. Using sqldf:
