c3 | The C3 , SMT/SAT solver written in C | Email library

I have a permutation of different electrodes (25x25=625) from frontal to parietal.

I have a CSS-type cubic bezier where
A = 0,0
B = a, b where 0<1
C = p, q where 0

<1
D = 1, 1

I want a function pointOnBezier(a,b,p,q,x) => {x:x, y:y}
I've found this which helps but no mathematical formula😓

Any help would be appreciated. Thanks in advance!!!

I know there are some other questions (with answers) to this topic. But no of these was helpful for me.

I have a postfix server (postfix 3.4.14 on debian 10) with following configuration (only the interesting section):

Basically there are rectangles (buildings) and circles (people).

The task I need to do is basically, when a function "fg" is called, every circle that is inside a given radius needs to run to the closest rectangle, and after all the circles inside the radius finds a rectangle, I need to report on a .txt file the names of the circles that run to each rectangle sorted alphabetically.

Such as:

Rectangle A: c1 c2 c3

Rectangle B: c7 c11 c20

...

And so on...

I need to store the addresses of the circles that run, on a vector of each rectangle. I tried to use qsort from stdlib.h, but maybe the function that i use to compare is wrong

(EDIT - full code to better understand):

In R, I can take a df and get a list of frequency tables for each sample/group by doing the following:

I have these data in my booked_tickets table:

1st Row: A1, A3, B2

2nd Row: C3, D2, A2

3rd Row: C1, A2, D1

When I tried to concatenate these data into one string, I get this: A1, A3, B2C3, D2, A2C1, A2, D1

What I wanted is: A1, A3, B2, C3, D2, A2, C1, A2, D1

How do I concatenate like that?

I have put example dataset (df), expected output (df2) and my code so far below. I have a df where some rows in column i2 contain a list - in the json format, which need exploding and reinserting back into the df, from the row in which they were extracted. But the need to be inputted into a different column (i1). i need to extract a unique identifier (the 'id_2' value) from the string and insert that into the id_2 column.

in my code so far i am parsing the json-like data with pd.normalize, and then inserting the original string from the column i1 onto the top of the extracted strings (it should be much more clear if you take a look below) and then reinsert them based on the index. But I have to specify the index, which is not good. I would like it to be less dependent on manual input of indices in case it changes in the future with more of these nested cells or somehow the index changes.

Any suggestions are very welcome, thanks so much

example data

I come from .net background and new to typescript. I have an array that contains objects from different classes that implement a common interface. I would like to check if the array contains an object from a particular class. I tried using a combination of 'includes' and 'instanceof' but didn't succeed. Thanks in advance.

Suppose classes 'C1', 'C2' & 'C3' implement the interface 'Int1'. Array 'array01' can hold the objects of classes that implement interface 'Int1'.

I'm a programming newbie so please bear with me.

I currently have a sheet, Sheet1 "DataSheet", holding string (text) data over an undefined amount of rows in Columns A, B and C. Sheet2 "BlankSheet" is a template "Score Card" which I must duplicate indefinitely based on total rows of data entry in "DataSheet". I did this using a command button.
