Ask HN: Which is that site which gives learning path for learning algorithms

60 points by 4444 ↗ HN
Few days ago I came across one site which gives a nice path and modules by modules progress of learning and practising algorithms. I forget the site name, do you have seen any products like this ?

What kinds of algorithms? What area: Science? Engineering? Math? Computing? Machine Learning? Optimisation? Sorting? Artificial Intelligence?

A clue would help ... what do you remember?

It was related to programming interview, computing only and there was a very well structured path as well.
sounds very much like https://www.interviewbit.com
This is what I had in mind as well. The difficulty ramps up quickly! I just had to do a couple of these and felt confident enough to start applying to jobs.
Not affiliated, just a user, but if you're looking for guided learning for interview specific algos and problems, etc, I used interviewcake with great success
Hackerrank is probably what you are thinking of
Classical engineering? Architectural? Electrical? Et. al?
Coursera and Udacity have some excellent courses by the likes of Robert Sedgewick.
Probably this one? https://roadmap.sh/ I have seen it few times last year, so could be. Although I would say it lacks the part of 'practising algorithms'.
It doesn't seem to say algorithms. Am I missing something?
Might be Exercism?

https://exercism.io

Btw its not the same, but it is really close to what I am searching and what I have seen , the only diff is the site you gave is language oriented, the one m looking for is totally based on DSA
Might be project Euler where you learn how to solve mathematical issues with algorithms
