SLR | Monte Carlo Ray Tracing Renderer | GPU library

I need to read this XML file - extract below...

i have an SLR (sign language Recognition) task, and i want to show the preprocessing part, here is my code :

Im a newbie in c++ and recently discovered classes;

I learned about constructors, overloading operators, the rule of three and right now i tried to learn inheritance.

I created 4 classes: 2 parents, 2 childs, but i occured some problems in class parent1

This is class parent1:

My problem is for the mtcars data set in R, I need to create all possible additive linear regression models where I'm regressing on the mpg variable. The null model is easy, as there's

10 choose 0 ways to get the null model, and 10 choose 1 ways to create a SLR on mpg; 10 choose 2 ways to create a two variable regression on mpg; 10 choose 3 ways to create a SLR on mpg; etc.,

So in total, as this is equivalent to summing across the 10th row in Pascal's Triangle, the total models I need to consider comes out to be 1,024.

Now, the other tricky part is I need to somehow store each model in some separate object so that all the 2 variable models are grouped together, all the three variable models are grouped together, etc, on top of also storing all them together (though perhaps there's a more efficient way to do this). The reason for this is my task is to look at all of these models, take their AIC scores and their Mallow's Cp scores, store those in a data frame, and then sort those scores from lowest to highest and keep the top 10. On top of this, I need to also be able to store, see, and have access to/use the two best 1-variable models through the two best 10-variable models because I need to provide the r-squared values and adjusted r-squared values for these various models along with the error mean square value. I'm still pretty/relatively new to R/coding in general, but I provide my attempt below:

Im looking at some Species of amphibians/reptiles found in a rainforest reserve using two different survey methodologies. I want to compare the methodologies, but one methodology has a lot more data than the other.

Within the study site, there are also three different zones with different levels of disturbance (CCR, PCR, and SLR), these also have varying amounts of effort to one another within and between the two survey methods.

I want to create two extrapolated species accumulation curves for each methodology, one including all disturbance types and another with the disturbance types split up.

I've managed to create the accumulation curves, but they are not extrapolated past the number of individuals observed. How can I extrapolate the curves?

Can someone help please? I have an editable table with column sum, using HTML and JS.

I tried to add a row, it's working but when I enter value on the new row, my total column is not changing dynamically, it's changing only after I use another row.

I just want to find how when I'm adding a new row and edit value content, it's changing the total of my column dynamically, not only when I used another row.

(Sorry I'm still training, if it's not perfect, I'm here to learn from my mistakes.)

Thanks,

Here is my code :

I have written a program using selenium in python flask which does webscraping of a product. My intention is to first enter the product name(this is done programmatically)->after product is displayed-> it should display the price of product which I would be displaying in the terminal. My issue however is that it doesn't scrape the website and it throws a Selenium NoSuchElementException. Here is my code.

I am scraping a website to get the product price using selenium. The program does work like it should ie. The intention is to Enter the product name(which is done programmatically)->after product is displayed-> it should display the price but I get an empty list. The price is not getting printed. Here's my code.

I'm learning Go and trying to implement it. My JSON data looks like this:
