Creating procedural terrain I cannot get an evaporation matrix and find why my algorithm is wrong. How my program works:

• A user loads a map chunk.
• If it exists it loads its data.
• If it doesn't exist, it creates the chunk and returns the generated data.

Creation of chunk steps:

• Create a heightfield (Diamond Square algorithm).
• Create [0,3] rivers (and more chunks if river needs to continue on a different chunk).
• Calculate evaporation.

When generating the terrain I use the following constants:

So I'm creating an R shiny app where I need to upload a few files and operate on them to output some (let's say 3) plots. So in every renderPlot() function in server I need to repeat the operations for it to work (code is chunky now). I was wondering if there's any way to assign the ingested file and operations to a global variable and access it in every renderplot() function? Is there a way to actually access it outside the server() at all (I've been told no)?

In other threads, I was told to use reactive() or reactiveValues() but to no avail. Below is the sample code:

I have two dataframes, the one contains Reviews for cars and the second one contains the car make and car model. What I would like to do is use the car model df_brand['name'] to be used to lookup every word in the Review sentence df['Review'] and remove matching words. I would like to remove all the words that contain car brands in them.

Input data df['Review']:

I am trying to convert a input sentence Review into a CountVectorizer. I am struggling to handle the sentences that are passed through. How do I deal with the sentences and add vectors to these? Any assistance will be highly appreciated.

I am trying to run sentences through the Porter Stemmer algorithm, however am getting and error: AttributeError: 'list' object has no attribute 'lower'. can anyone assist, as I am not able to identify the problem:

I'm building a scraper with selenium, and I got it up and running except for one data field I'm missing. I need to first push a button, then get the value. But I haven't been able to push the button, because I can't seem to build the correct xpath expression to get it with selenium,

The url is this one: https://www.ikea.com/mx/es/p/kallax-estante-blanco-80275887/

And I need to click the button "Medidas" (scroll halfway through the page, right between "Detalles del producto" and "Productos similares") to open a side panel and get the info I need. But so far, I haven't been able to set the correct XPATH expression for the button.

I tried with

I'm writing a program that dynamically allocates an array, on the heap, fills it with random numbers from 55-99 and prints them out in 10 rows. I'm using 9 more dynamic arrays to store each of these rows. But when running the program I get the error: HEAP CORRUPTION DETECTED after normal block. I'm sorry for the chunky code.

update when i write (as answerer said)

In an exercise I am asked to reorganzie a tuple. Given the tuple: temp = ( ("mandag", 16.0), ("tirsdag", 13.0), ("onsdag", 14.0), ("torsdag", 13.0), ("fredag", 15.0), ("lørdag", 13.0), )

I am supposed to write a function called data_reorganize which outputs the following tuple when printed:
