I am trying to make a program that sees if a word is a palindrome or not. However, I am getting the above error. When I run the program it puts together the word backwards, up until there are no more letters left. That is when I get the error.

I am creating a program, and I have a rectangle. Basically, I am creating a custom window inside the SDL2 window, which is a Rect, with another Rect being its toolbar. I am struggling for hours trying to figure how to detect how deep is the mouse within the Rect, but I am failing every time. The most obvious equation for me was int deep = mousePos.x - x, but it flickers between two positions every time I move my mouse. I then have tried a LOT of other calculations, but none of them worked. Either they flickered between two positions with descending values, or they were completely static and didn't move, or always moved a lot in a specific direction. I have visually represented the calculations, which were mostly correct, but the flickering between two positions is always ruining it. Thanks for any help. I am providing source code, too.

I have created a very basic gradle java project that prints "Hello Word". The main class builds and runs fine. When i try to run java -jar out\artifacts\helloWorld_jar\helloWorld.jar on the command line it gives me this error

Example

I have a dataframe column that lists information on the year a particular property was built. The value can be: a year, unknown or newly built. I want to replace all the "newly built" values with current year, keep the year values as is and replace all the "unknown" values with the average of the column. Here is my code:

I am creating a game in SDL2 and C++. While I have a lot of experience in other programming languages, I haven't coded in C++ for years, and wanted to try it out again. Anyways, I've discovered a C++ library called SDL2 and decided to create a game. The idea for the game is still not chosen, but I am trying to create a "virtual window", which is basically just a rectangle you can drag around and show content in it. I've done almost everything, except the drag part. I want to drag the window's toolbar, and move the whole window with it according to my mouse position. Basically, I want to put the mouse in the toolbar, and when clicked and dragged, I want the whole window move with the mouse, but almost all of my attempts are that the whole window teleports at the end of my mouse, so I can't move it to the left, only to the right and down. I've found a potential way, which is included in the source code, but the window always switches positions. I don't really know how to explain this, but it switches e.g at one frame, the X is 68, at the next it's 271, and at the next one it's 67 (68-1), and at the next it's 270 (271-1) etc. I am including the source code with my post.

The "Window" class:

I'm getting the following error and can't seem to find a resolution beyond changing the argument names which I would rather not do:

So I have found this code through W3Schools and I have changed it to my liking for my school project. Currently, it is a dropdown that when typed into removes the results that aren't spelt the same. What I'm looking to do is reverse this where they all start hidden and when the result is typed in it will show, many thanks!

I have a route/view in my Flask application where I am editing an existing record and I want to ensure that my changes are only committed to the database if I am updating the latest version of the record.

For example, my application has a Vegetable object, which has a field called name. The "Edit Vegetable" route/view is based on a form in which the name field is first populated with the existing value for the Vegetable.

Scenario 1: User A opens the "Edit Vegetable" page for a specific record. The name field is populated with the existing name of "Courgete". As this is not spelt correctly, the User is going to change it to "Courgette". However, they get distracted and don't press the Save button for a few minutes. In between them editing the name and pressing the Save button, User B, their colleague from the USA, opens the page for same record, changes the name to "Zucchini" and saves it. I would like User A to get a warning or even prevent them updating the record when they press the Save button as they are effectively no longer editing the latest version of the record.

Scenario 2: User A goes back through their browser history until they get to the previous Edit Vegetable record where they originally changed the name of the Vegetable to "Courgete". Again, I would like a warning or to prevent User A pressing the Save button and updating the record, as again, they are not updating the latest version of the record.

I am newbie, and in all of the tutorials that I have looked at, these considerations are not mentioned and I have not been able to find a solution through a web search, though that might be because I am not searching with the right terms. I tried having an updated datetime on Vegetable object that gets updated when the record is updated. However, I couldn't work out how to then check this as before it seems that before it does the update, the POST reloads the Vegetable object. Below is a simplified version of my code. I am using Flask-WTF and sqlalchemy.
