I have some messenger group data parsed from JSON. I'm trying to get some statistics from it.
Am I missing something obvious about the map/filter/reduce powers by doing a big for loop of filters? Would this pass code review for an internal analytics tool?
people.forEach(function (person) {

I have written BST in java for practice. Need inputs. On, how to write better unit test cases. am sure the way I have written is not proper.

I have this code in python (using django firmware) that connects to an external API and update some values in that service. Each step depends on the previous step (for step 2 to work step 1 must return True and so forth that include a valid connection to the API). How can I insure that all of the...
It's an exercise from a Swift-course I'm currently taking.
You are given an array of integers. Make an additional array named
computedNumbers. computedNumbers should multiply each element in the
numbers array by the next following element. The last element shall be
multiplied by the fi...
I think the part to get shortest path from the cost table got pretty messy. Also can use some tips on how to avoid the extra work checking all edges from source to dest after getting the cost table, or have a better optimized implementation in general.

The fact is that I wanted to apply the builder pattern. But this could not be achieved, since I could not create an instance of the class with an empty constructor - this is dangerous. The goal is to make the parameter list a little shorter and more meaningful. As a result, I created a new class,...
Find HCF and LCM possibility length pairs from any single number
Example:
If you pass 4 its output should be like
{0, 1}, {1, 0}, {1, 1}, {1,2}, {2, 1}, {2, 3}, {1, 4}
Find out length of pairs

Someone help me in telling that what program wants to compute, I couldn't understand the question.
My React application manages some entities. I'm using Redux (with redux-thunk) to manage the application state. I've created a RESTClient based on Axios:
export class RESTClient<E extends { id: number }> extends Client {
protected path: string;
public constructor(path: string, token?: string...
I was recently going through some OpenCV code that finds the center of mass in a contour and realized there is potential room for optimisation.
What I noticed looking back through my code is when I calculate the mass I'm using contours.size() which makes me believe that I'm calculating the momen...
Haskell newbie here. I use ghci to implement a baby quicksort algorithm [1] as follows:
Prelude> quicksort (firstx:xs) = quicksort[x|x<-xs, x<firstx] ++ [firstx] ++ quicksort[x|x<-xs, not(x<firstx)]
Prelude> quicksort [] = []
The command quicksort [1,2,3] then gives an error:
*** Exceptio...
