QUESTION
With a given number with no repeating digits, I want to add the correct amount to get to the next number that has no repeating digits it it. This may be as simple as adding 1, or adding hundreds as it gets complex when the given number is high. Examples of numbers with repeating digits in them are 11, 345675, 4335, 24364. Examples of numbers with no repeating digits are 12, 735691, 89, 623490.
An interesting point to make is that there will never be more than 2 repeating digits in a number when caught as soon as it repeats, nor will multiple sets of repeating digits. For example, numbers 1232, 654334, 765661 will never come up.
Some conditions I do not want to occur. I do not want there to be loops counting up and just returning numbers that have no repeating digits. I want the program to be able to take a number with no repeating digits and know how many to add by dissecting and evaluating the number.
An example of what I do not want. This just loops until it detects a number with no repeating digits.
...ANSWER
Answered 2021-May-02 at 15:48First, you increment the number by 1. If this number has no repeating digits, you are done. Else, you can follow the following algorithm.
(We look at the number as a string.)
- Locate the first repeated digit.
- Mark it as a "location to change" (
change_at_locationin the code). - At a location to change, increment the digit to the next highest "available" digit (i.e. a digit that is not repeated till that point in the number). [Note: Such a digit might not always be available, since all the higher digits might already be used.]
- IF such a digit is available,
- Increment the digit at the location to change.
- After that location, look at all the available (i.e. unused up to that point) digits in the increasing order, and insert them one by one.
- ELSE
- Move the location to change back by 1
Note: If location to change reaches -1, insert a dummy '0' at the start, and update the location to 0, and redo the whole thing.
Following are two snippets, one with the loop, the solution you don't want, but is simple to convince ourselves that it "works", and second without loop using the above algorithm.
QUESTION
I would like to first explain what this application/Python program does so that you have a better understanding of the problem. I am an absolute beginner in programming so please take it easy on my i have tried my best to explain it as vividly as i could. This application will be used to test 4000 devices for there correct software hardware version and other information. How it does this is through the Web-server, each device has a 2D code(its like a barcode) which will be scanned, this scanned code contains the mac address and the ordernumber. firstly when i run the program on command prompt it should look like this : I should be able to define what the desired variables are hence typing it manually in the command prompt EXCEPT for the scancode which will automatically appear when I used the 2D scanner and scan the code which will be on the device exterior. The scancode contains the devices mac address(last 12 digits) and the Order number(first 5 digits) i found out how to dissect it and compare it with the webserver's Mac address and order number.
Once i have defined the desired values for Order number Hardware version Software version etc these "desired" values need to be compared with the webserver values. (Please see my Python code for reference i take the webserver values through xml.dom and then compare it with the desired values to see if the values are correct. So far i have only manually defined the desired values in the source code but I want to define them on the command prompt line after calling the programm "C:\Users\Barry\Automate main.py" I hope you guys have understood the problem i am facing, I want to know if anyone can help me solve this task i have googled a so much about this but i cannot find out how to do it. In the picture i have uploaded the values underlined in red are to be manually input and the blue one is the scan code which will automatically appear when I scan the device. I tried several things with input() method but yeah it did not work out example:

Here an example that will help you understand how to use it:
QUESTION
The R Language Definition makes several mentions of the model formula operator, but fails to define or explain anything about the formula class.
I am having a hard time finding anything that documents the semantics of the ~ operator from either official or unofficial sources.
In particular, I am not interested in information like is provided in the formula function documentation ("An expression of the form y ~ model is interpreted as a specification that the response y is modelled by a linear predictor specified symbolically by model.") or usage scenarios, I'd like to understand what kind of data structure I am creating when using it and how I could inspect and dissect it on the REPL.
...ANSWER
Answered 2021-Apr-25 at 01:08Don't know if this helps, but: it's a language object — i.e. R parses the input but doesn't try to evaluate any of the components — with class "formula"
QUESTION
I'm trying to understand the zero-crossing method for frequency estimation. After searching, found this code:
...ANSWER
Answered 2021-Apr-22 at 07:40I am not sure where you got the sampling frequency from (framerate) but in digital signal processing there is this thing called the Nyquist frequency where you cannot sample reliable more than half the sampling frequency, which may explain your factor 2. Do note that in your code the division is different from the snippet.
It should be freq = framerate/(average_of_total_points/2)
QUESTION
I am trying to parse my Log message to a JSON format.
I have the next JSON message as input in LogStash:
...ANSWER
Answered 2021-Apr-21 at 09:52If the format is always in the same order you could look into using the grok filter plugin: https://www.elastic.co/guide/en/logstash/current/plugins-filters-grok.html
The pattern i think might do the trick, if you want to use the numeric value of the time as seconds you can change the pattern a bit, as well as for the file size...:
QUESTION
I'm implementing Rust Cargo version requirements. In general, I have trouble understanding caret requirements as specified. I found What's the difference between tilde(~) and caret(^) in package.json?, but this question is about npm version requirements of which I'm not sure if it is the same as Rust Cargo version requirements.
At https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#caret-requirements, I read:
Caret requirements allow SemVer compatible updates to a specified version. An update is allowed if the new version number does not modify the left-most non-zero digit in the major, minor, patch grouping. In this case, if we ran
cargo update -p time, cargo should update us to version0.1.13if it is the latest0.1.zrelease, but would not update us to0.2.0. If instead we had specified the version string as^1.0, cargo should update to1.1if it is the latest1.yrelease, but not2.0. The version0.0.xis not considered compatible with any other version.
Here are some more examples of caret requirements and the versions that would be allowed with them:
...
ANSWER
Answered 2021-Apr-12 at 16:39Unlike in npm, the default version requirement range is indeed the caret requirement! This is stated in the Cargo reference on "specifying dependencies", just before the section linked in the question.
The string
"0.1.12"is a semver version requirement. Since this string does not have any operators in it, it is interpreted the same way as if we had specified"^0.1.12", which is called a caret requirement.
As such, the following two dependency specifications are equivalent.
QUESTION
In an Excel file I have two large tables. Table A ("Dissection", 409 rows x 25 cols) contains unique entries, each separated by a unique ID. Table B ("Dissection", 234 rows x 39 columns) uses the ID of Table A in the first cell and extends it. To analyze the data in Minitab, all data must be in a single long row, meaning the values of "Damage" have to follow "Dissection". The whole thing looks like this:
...ANSWER
Answered 2021-Mar-18 at 18:59I highly recommend using pandas for situations like this. It is still a bit unclear how your data is formatted in the excel file, but given your second option I assume that the tables are both on different sheets in the excel file. I also assume that the first row contains the table title (e.g. Table A - i.e. Dissection). If this is not the case, just remove skiprows=1:
QUESTION
Original Problem - CSV file is too big (700k) records - so looking to create smaller CSV files from that big CSV file.
Got the following code to dissect the file and create smaller files.
...ANSWER
Answered 2021-Mar-10 at 22:02As I commented above, the fix is to call Flush on the CsvWriter prior to copying the MemoryStream. The issue is that there is a pending data still sitting in the CsvWriter internal buffers that doesn't get copied to the MemoryStream until you Flush it. That should get things working for you.
However, I have deeper feedback for your scenario. It appears that you are reading the entire 700K file into a List before you process the batches. A better way, would be to stream the CSV data from Azure and as you are a reading it send the smaller batches back to Azure.
In this example I'm going to use my own library (Sylvan.Data.Csv), but I'm sure CsvHelper provides similar capabilities.
