[v3] Add prerequisites 3/6

[TomPradat]

⚠️ If you have issues / are unsure, create ONE PR PER EXERCISE so it's easier to merge them as we can have discussions per exercise. If you're certain, it's fine to do a single one.

The idea is to split #960 into smaller chunks.

Here is the list of practices exercises to deal with for this part :

anagram

acronym

high-scores

isogram

matching-brackets

phone-number

scale-generator

series

largest-series-product

transpose

grep

rectangles

spiral-matrix

ocr-numbers

saddle-points

forth

food-chain

house

isbn-verifier

pig-latin

I am willing to take this issue up (at least some of the exercises). Just let me know if I should make the PRs, one for each exercises, one for a batch of exercises or one for all of them.

I'd suggest that you make a PR for each exercise but if you feel like you want to do a lot of exercises you can take 4-5 by PR.

Trying to do all of them at once is not a good idea IMO, it's indigestible for both you and the reviewer.

Idk if this might help but here are the steps I used when doing some :

1 - Doing/trying the exercise
2 - Looking at the exercise's proof of work
3 - Looking at the submitted solutions.
4 - Adding the prerequisites

Good advice from @TomPradat there. I am in favor of a batch of max. 5 exercises per PR.

Sounds good to me
