Leetcode type problem - Sub-Arrays problem

Generate number of sub arrays with a particular sum: E.g. nums = [1,1,1] with sum 2

arr = [1,1,1]
SUM =2
#arr = [1,2,2,3,4,5]
#SUM = 5

sub_arrays = []
arr = arr.sort

arr.each_with_index do |n, index|
  if n == SUM
    sub_arrays << [n]
    next
  end
  rest_of_array = arr[(index+1)..-1]
  temp_arr = [n]

  rest_of_array.each do |m|
    temp_arr << m
    if temp_arr.sum == SUM
      # We found a sub_array!
      sub_arrays << temp_arr
      # There might be duplicates of m, so let us remove m from temp_arr and continue
      temp_arr = temp_arr[0..temp_arr.length-2]
    end
    if temp_arr.sum < SUM
      # do nothing; we can continue to add more elements
    end
    if temp_arr.sum > SUM
      # discard all elements except n
      temp_arr = [n]
    end
  end
end

https://www.ninoristeski.com/how-to-find-the-best-resources-on-machine-learning/

...

Start with tabular data and linear/logistic regression. Then grab lightgbm with automl, learn the common explainability methods and focus on anything BUT selecting an algorithm. When you got that, learn all other algorithms in and out and look for model innovations.

...

Just learn BigQuery and it's machine learning capabilities and read books alot and avoid youtube videos as much as possible.

...

Start with SQL, Python. Pick a popular ML library e.g. Sklearn, Keras, XGBoost and apply it to a dataset

...

Start by getting familiar with the fundamentals of machine learning, such as linear algebra, calculus and probability theory. Also read up on popular algorithms to get a better understanding of how they work.

...

Learn statistics and probability a lot of concepts require simple concepts from those fields, if you want to go a little further learn abstract geometry is going to allow you to learn about how nonlinear models implement hyperplanes.

Prerequisites for Algorithms by Jeff Erickson

Author lists below as the prerequisites for reading his book: (Below content has been copied from the Prerequisites pages of his book)

• Discrete mathematics: High-school algebra, logarithm identities, naive set theory, Boolean algebra, first-order predicate logic, sets, functions, equivalences, partial orders, modular arithmetic, recursive definitions, trees (as abstract objects, not data structures), graphs (vertices and edges, not function plots).

• Proof techniques: direct, indirect, contradiction, exhaustive case analysis, and induction (especially “strong” and “structural” induction). Chapter 0 uses induction, and whenever Chapter n−1 uses induction, so does Chapter n.

• Iterative programming concepts: variables, conditionals, loops, records, indirection (addresses/pointers/references), subroutines, recursion. I do not assume fluency in any particular programming language, but I do assume experience with at least one language that supports both indirection and recursion.

• Fundamental abstract data types: scalars, sequences, vectors, sets, stacks, queues, maps/dictionaries, ordered maps/dictionaries, priority queues.

• Fundamental data structures: arrays, linked lists (single and double, linear and circular), binary search trees, at least one form of balanced binary search tree (such as AVL trees, red-black trees, treaps, skip lists, or splay trees), hash tables, binary heaps, and most importantly, the difference between this list and the previous list.

• Fundamental computational problems: elementary arithmetic, sorting, searching, enumeration, tree traversal (preorder, inorder, postorder, levelorder, and so on).

• Fundamental algorithms: elementary algorism, sequential search, binary search, sorting (selection, insertion, merge, heap, quick, radix, and so on), breadth- and depth-first search in (at least binary) trees, and most importantly, the difference between this list and the previous list.

• Elementary algorithm analysis: Asymptotic notation (o, O, Θ, Ω, ω), translating loops into sums and recursive calls into recurrences, evaluating simple sums and recurrences.

• Mathematical maturity: facility with abstraction, formal (especially recursive) definitions, and (especially inductive) proofs; writing and following mathematical arguments; recognizing and avoiding syntactic, semantic, and/or logical nonsense.

Books:

Margaret M. Fleck. Building Blocks for Theoretical Computer Science, unpublished textbook, most recently revised January 2013. Available from http://mfleck.cs.illinois.edu/building-blocks/.

• Eric Lehman, F. Thomson Leighton, and Albert R. Meyer. Mathematics for Computer Science, unpublished lecture notes, most recent (public) revision June 2018. Available from https://courses.csail.mit.edu/6.042/spring18/. (I strongly recommend searching for the most recent revision.)

• Pat Morin. Open Data Structures, most recently revised January 2016 (edition 0.1Gβ). A free open-content textbook, which Pat maintains and regularly updates. Available from http://opendatastructures.org/.

Rails related: Concerns, Module-method extraction Vs Class-based extraction, Concerning module

1) Single-use Modules are probably better off as Classes as per the below article.

https://www.cloudbees.com/blog/when-to-be-concerned-about-concerns

By and large, maintainers tend to agree that smaller composable classes are the best way to isolate code and keep things clean.

....

I'm not saying that you need to go out and refactor all your single-use modules into classes. I am saying if you find yourself reaching to do a module-method extraction, stop. Consider what road you're starting down and these lessons I've shared. What would a class-based extraction look like instead?

2) https://blog.appsignal.com/2020/09/16/rails-concers-to-concern-or-not-to-concern.html

Draft Pull Requests

https://software.rajivprab.com/2021/12/26/our-engineering-principles-and-best-practices/

Draft Pull-Requests
For each pull-request, first create a draft pull-request, demonstrating the proposed implementation at a high level. Use TODOs and placeholders to indicate which classes/methods you will be touching. Send it off for review and then immediately start working on the actual code and tests.
This mitigates the amount of wasted effort, if your reviewer then suggests a completely different way of implementing things. Once your reviewer approves the draft, link to it in your pull-request, to make sure everyone knows what was already discussed and agreed on.
