Integer factoring is the decomposition of an integer into factors that, when multiplied together, give the original number. For example, the factors of 15 are 3 and 5.

QUESTION
I'm writing a calculator script in Python 3 which takes 3 variables from a for loop: A, B, and C. This is for factoring a polynomial. So here below is the script which takes in A, B, And C:
...ANSWER
Answered 2021-May-18 at 03:11That's not how you do it. You store the input variables in a list, then you pull them from the list.

I am trying to efficiently compress sets of numbers which look like this (one set per line):
...ANSWER
Answered 2021-Apr-26 at 00:45We can combine three simple ideas:
Encode the symmetric differences between successive sets (I think this is what Mark is suggesting).
This is good for encoding but hard to decode randomly. To fix it, emit the whole set periodically. One heuristic is to do this whenever we've emitted approximately as much in deltas as the whole set -- in theory, this costs only a constant factor more in storage while limiting the total size of the deltas we scan to a constant factor more than the size of the set.
Use a delta encoding with varints. This is a common encoding for posting lists, so there should be optimized implementations floating around.
Python 3 encoder that compresses the given input to less than 5 MB. We also need an index, but this won't add much.
QUESTION
I have a data frame which looks like this:
name pos1 pos2 pos3 A 0.56 0.2 0.24 B NA 0.72 0.1 C NA NA NA D 0.1 0.02 0.1The list goes on to ~500 rows.
In the prediction dataset, I want to set TRUE as any position having a number greater than 0.5. I dont really care if it has a NA included, I just need to know that it has AT LEAST one position that has a value >0.5.
However, I dont really need the rows that have NA for all of the positions.
The current code I have is :

QUESTION
I inherited some code that I'm in the process of re-factoring, and I came across something where I'm uncertain of the intention. Many (more or less all) of the classes have defaulted to the below pattern, where it appears as though memory management is intended to be handled with a static std::set.
...ANSWER

DestructAll_A()does not call A's destructor
Yes it does. Obj has type A*, so delete Obj will call the A::~A() destructor. This is undefined behavior for any instance that wasn't allocated using scalar new A().
Lastly, it's unclear to me how it would be differentiated instances of A that were statically vs dynamically constructed (using new).
It doesn't attempt to differentiate... this class must never be used except with scalar dynamic allocation.
QUESTION
So I needed to re-work a data import and I saw the NHS Data Dictionary package had been released for R so I thought I could use it to map the 1's and 2's in my Gender column to more usefully named factors (i.e. Male and Female), I can never remember which is which so they definitely need sorted.
My example dataset:
gender age 1 40 2 43 2 56 1 72 9 34Getting the data from NHS Data Dictionary with the new package is easy enough - if a little heavy on the typing...
It would be easy enough to do a join to my data, but that 'feels' the wrong way in this case.

QUESTION
https://www.primefaces.org/primereact/showcase/#/datatable https://www.primefaces.org/primereact/showcase/#/multiselect
I am using the PrimeReact library to create and customize a Data Table.
My table is dynamic and will build itself based on the data given to it. I am assigning different filters to each column depending on the column's data type, but because there are a variable number of columns I must create the filters dynamically.
To accomplish this I am factoring out the filter logic into a separate class which contain their state and logic.
My issue is that the MultiSelect component I am using as a filter interface does not update its value when it's value's state is updated. After updating the state the value remains null. As the MultiSelect component does not have a reference to the previously selected values I can only choose one value at a time.
I think I am missing some understanding regarding class components, as I usually use functional components. I used a class component in this case so that I could access filterElement from the instantiated DropDownFilter class through DropDownFilter.filterElement() and use as a prop in the Column component.
...ANSWER
Answered 2021-Mar-07 at 22:17I learned the state was not working in this case because I was instantiating the DropDownFilter using the new keyword in when using it. This means it wasnt being mounted to the DOM and could not use state.
I am still having issues regarding implementing the custom columns with filters, but I have posted a new question to handle that scope with my new findings.

Install factoring
You can use factoring like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
