I have done a couple of contests in codechef and I have found tat my main handicap is algorithms. Please suggest a book to learn about algorithms related to optimization, dp and data structures like trees and graphs

Thanks a lot
Also, once you learn about a certain algorithm, I recommend finding a problem to solve that requires it. For example, if you want to learn Dijkstra’s algorithm, first read about how it works, then try problems like these:
Tutorials usually give you exhaustive explanations for an all-inclusive setting, but I find it helpful to just gather what I can from there and immediately apply it to a much simpler actual problem. It then becomes much easier to expand to more generic situations, once you have a handle on the basic concept. Make the algorithm your own. Also, editorials are your friends.

welcome
Thanks a lot. Really helpful suggestion
Hello @danieljeswin,
You can visit this link. It has most probably all the algorithms and data structures along with tutorials and problems in them.
[Data Structures and Algorithms][1]
Happy Coding

There are several great books for learning - two that are commonly cited are Algorithms 4th Edition by Sedgewick, and Introduction to Algorithms 3rd Edition (CLRS). Personally, I found the latter easier to follow and better explained but I know people who feel the opposite.
P.S. if you liked my response please upvote - since I am a new member I need karma points to do basically anything on this site

The best way to learn is practice. Whenever you learn some topic you can practice it over here …
