Answers.Text: Leetcode is generally not terribly theoretical. You need basic complexity (the difference between quadratic and linear, mostly), graphs (DFS/BFS), n-ary trees, arrays, strings, DP. Using CLRS to prepare for LC is overkill and will dip into randomized algorithms, FFT, ML, NP completeness, max flow, creating hash tables from scratch, self-balancing trees, and other theoretical topics that have little to no bearing on LC (not that they aren't great on their own terms, just less relevant to LC, and should be reserved for later when a special occasion arises).

Answers.Text: I found the 1990 edition of Sedgewick's _Algorithms In C_ very readable and enjoyable — it explained enough of each algorithm to give you the idea and enable you to go off and start coding it, but not enough to be dry and tedious. (I've only glanced at more recent editions, but my impression was that they're much more detailed and less fun.)

Comments.Text: What makes you think you need a book before starting? All topics are tagged, so you can pick basic problem, work up to harder problems, and search for particular concepts as you need them. Algorithms and data structures are huge topics, so starting with the book may result in a lot of extra information that's hard to see the purpose of.

  [Cormen's, Leiserson's, Rivest's and Stein's *Introduction to Algorithms and Data Structures*](https://rads.stackoverflow.com/amzn/click/com/0262033844) is widely considered a most great book on the topic in question.
  
  Even when googling ["best algorithms and data structures book"](https://www.google.com/search?q=best+algorithms+and+data+structures+book&sxsrf=ALiCzsZ5I-dytHJJnMHcmYHgrK4U1t-ANg%3A1657538086381&ei=JgbMYuTzFvHFrgTC_rC4DA&ved=0ahUKEwjkntzG2vD4AhXxoosKHUI_DMcQ4dUDCA4&uact=5&oq=best+algorithms+and+data+structures+book&gs_lcp=Cgdnd3Mtd2l6EAMyBQgAEIAEMgUIABCABDIGCAAQHhAWMgYIABAeEBYyBggAEB4QFjIGCAAQHhAWMgYIABAeEBY6BwgAEEcQsAM6BwgAELADEEM6CggAEOQCELADGAE6EgguEMcBENEDEMgDELADEEMYAjoMCC4QyAMQsAMQQxgCSgQIQRgASgQIRhgBUKYEWJ4GYI0HaAJwAXgAgAF1iAGrApIBAzIuMZgBAKABAcgBDsABAdoBBggBEAEYCdoBBggCEAEYCA&sclient=gws-wiz), [first](https://www.tableau.com/learn/articles/books-about-data-structures-algorithms) [few](https://www.interviewbit.com/blog/data-structures-and-algorithms-books/) [links](https://www.guru99.com/data-structure-algorithms-books.html) place it at the top of their lists. Some even mention that it's sometimes called "the bible of algorithms".
  
  That book covers not only the basics, but also topics above the "standard" level of Leetcode exercises. I highly recommend starting with it. After you finish it, I believe the best course of action is to reserach individual topics that cought your interest.
  
  There is one more thing I would like to touch on. A mistake some people make is trying to read those kind of books from cover to cover and only afterwards jump into coding. This approach is, most of the time, very inefficient. Once you learn an algorithm or a data structure, try using it, implementing it, and tweaking it. Experiment with the knowledge you are gathering on your way, rather than trying to isolate it.
