Do you know good sites for algorithms and data structures?

This book is considered a good source for learning about algorithms: Grokking Algorithms: An Illustrated Guide for Programmers and Other Curious People

prepinsta.com for practical javatpoint.com for theory

Have you tried the courses in the community tab? I see their offer both stuff on algorithms and data structures. There are a number of lessons under those topics.

The Leetcode website is a place you can test what you know (algorithm solving practice)

I haven't gone through all the lessons myself but from a glimpse it looks like all the important topics are covered. I think it is good enough for an interview in terms of what is covered. If I am you, I would make myself well versed in these topics such that I know how and when to apply the algorithms or use certain data structures, so if you get asked in an interview, something like given a certain situation and the interviewer wants you to give a brief desription and design of how you would resolve the problem , you would know exactly what algorithms and data structures to use (assuming you are applying for a development job)

Geeks for Geeks

Vote for leetocode website. And its’ community and practices resources are great treasure to explore.

Paul K Sadler thank you! Is this enough for job interview?

Paul K Sadler Thank you very much! I'm a beginner in algorithms and data structures and would like to be intern/junior developer

Kresnt Mun yes, thank you!) But I don't know if this is enough for job interview

Well, that depends on how much you already know and the type of position you are applying for. Another good book is Cracking the Coding Interview by Gayle L McDowell

Aaron Yang thank you!

Genius Takudzwa Mubvumbi thank you!

Aditya thank you!

Kresnt Mun thank you very much!)
