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
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.
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]
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
You can study and practice different Data Structures and Algorithms here
I found it really helpful
The best way to learn is practice. Whenever you learn some topic you can practice it over here …
This website has many problems topic-wise and arranged on the basis of difficulty…
Thanks a lot
Thanks a lot. Really helpful suggestion
Thanks for the suggestions
Thanks a lot
