I want to make a getter that doesn't allow the caller to edit the returned object.

Using a List as an example (though I would like the answer to apply to any other type as well), this is the usual approach for returning and for editing an attribute:

I am making an App to save and display the seizure history of patients. As I am new to Flutter, I am having difficulty in how to store data in firebase for the current user at the time of seizure occurrence.

I am storing data in the real-time database, so for that, I am using the date as a child and if more than 1-time seizure has occurred then it will store the data with the new key under the same date, but let say if a seizure occurs tomorrow as well with date 3-6-2021, then how will it store the value with a new date?

Currently, data is storing like this:

How can I store data with the new date under the same child as Seizure_history?

My code looks like this:

So I followed the instructions here on how to take two inputs at the same time to execute a different function than either key press individually.

My code doesn't want to work but only the function that requires two key presses ('w', 'a'): upLeft and I can't figure out why. I tested my function in the provided solution and it worked. I can't seem to see any tangible differences between what I have here and what is provided in the link.

I'm trying to make lazy loading on vaadin grid, but I got error java.lang.IndexOutOfBoundsException: Index 0 out of bounds for length 0 Here is my UI code :

I am a beginner in google appscript. I do have a global variable called var streetSheetName = "JALAN SANGGUL 4"; but it is updating the value bro. The value should be updated in function checkLogin(username, password) but its not working. Would anyone mind help me with it. I have attached link to my appscript to explain myself better. Thanks in advance. Thank you so much.

I have a very large csv file (+50k lines).

This file contains IRC logs and here's the data format:

• 1st column: Message type (1 for message, 2 for system)
• 2nd column: Timestamps (numbers of seconds since a precise date)
• 3rd column: Username of the one writing the message
• 4th column: Message

Here's an example of the data:

I'm trying to make a C++ implementation of RB tree. But when I try to delete an element - I find out that some leaves of tree has different value of black height. Before calling remove functions everything works fine - insertion and rebalancing after tree insertion works correctly. But after a single call of remove function it isn't balanced anymore.

General remove:

I am stuck at this point, I am trying to clean the row name of a table using postgresql. The table is for districts in wales and England.

What I am trying is to delete the strings 'District', '(B)', 'London Boro' and everything before the hyphen in the dual English - Welsh name, for example (Swansea - Abertawe) I would like to eliminate everything before the hyphen (I would like to know how to do it in both direction anyway) and get (Abertawe). I manage with the first 3 strings but with the part of hyphen I cannot find the solution to the issue.

I have tried using replace and trim but I don't obtain the result desired.

This is code as I have tried the last time:

I have a dataframe that has a weird format that I am having difficulty formatting it to a desired format. I just need the columns first_name, last_name, domain, Email, Verification and status but am not sure how to remove it when it is in this format.
