Topics Problems
By 7oSkaaa, history, 23 months ago, In English

Good Day to you!

While a lot of us, when he begins to start competitive programming he found difficult to found problems on some topics in the beginning to practice of it, and same thing for a lot of ICPC Communites that they have started.

These are some topic not advanced and videos, problems and articles on them.


Prefix Sum & Frequency Array
STLS
Number Theory
Math
Binary Search
2 Pointers
Recursion
Backtracking
Bits
Graph
Dynammic Programming
Segment Tree
Ordered Set

Sorry for my poor english.

Are these problems introduced to people who struggled with B problems ?

      I'd mostly agree with you, but the last 4 topics have almost zero chance of ever appearing in a Div2B problem due to the pre-requisite knowledge required.

      If a problem requires Graphs or Dynamic Programming, nearly all problem setters and coordinators will not even consider putting it at any position less than Div2C. The same is true for SegTree or Ordered Set and Div2D.

      Disclaimer: I've only looked at the topic headings, not the actual problems, so I can't be 100% sure about the difficulty of the problems you've linked on these topics and am just assuming they're not too tough. Its certainly possible to set problems that are at the Div2F level or even higher using just one or two of these topics.

      Also, in my opinion just solving problems that are moderately difficult for you is a decent way of finding stuff that you need at your level that you don't know.

        I agree with you completely, the last four topics will be Div2 C or Div2 D, but not difficult for anyone who study these topics they are not hard and not easy, If anyone wants to train on these topics they will help them.

Hey ,

In case of graph sheets, do you have solutions or hints somewhere written so that we can refer to, in case of a difficulty.

    You can search on the name of the problem and get the original problem from the original contest and read the tutorial.

Currently I don't prefer topic-based practice anymore.It's better to do just randomly

    If you don't know 50% of these topics, you will be stuck in solving most of the problems, they will help you to practice on a specific topic to be good at it, but after that, you must practice in blind style to know how to solve the problem with which topic.
