        I think for cp there is no course required but for learning a language you can use youtube lectures and then come back to solve problems

          yep, i agree but if u go even farther out, u might need a course to teach u stuff like graphs, interactive, dp, etc. I'm talking if ur alone, no college/university, just u.

I went from practicing 1500 to practicing 2000+ in a few months by following Benq's editorial spam strategy. I'll admit it's not for everyone, but for lower rated people, it's great to get exposure to lots of new strategies.

      Sure. Open a question a bit higher than your current level, read it and try to solve it, and if you hit a roadblock for more than 5 min read the editorial then understand and implement.

          This will happen sometimes, I would store the problems like this somewhere and come back to it later.

          Also IMO lower rated coders should start on leetcode because of their better(and multiple) editorials in pretty much all languages.

As an Expert, I would suggest learning basics like binary search, greedy, math, DFS, BFS, easy DP. I think this is enough for specialist. Good luck

First of all know the basics like how to implement every thing come to your mind know the basics like stls binary search after that solve alot of problems to make the thinking skils good after that take topics like recursion , dfs , bfs , dp , basic number theory , after that solve alot of divs 3 and 2 and the most important thing is upsolving after you reach expert or high spishalist leran graphs (Floyd, bellman , dsu , kruscal ) and ds(segemnt tree ) i think itmo course will be good for you and take strings like (hasing , trie ,kmp , z algo) after you know this things solve on cses this will help you to know the idea of basics problems in many topics

Getting to master is mostly about IQ, so first take some high-quality online IQ tests to determine if you should pursue this goal.

      I think 130. You might find some masters with $$$<130$$$ IQ, but it would be pretty rare.

        I think IQ argument is valid: please check HERE https://codeforces.net/blog/entry/133722?#comment-1195893

        Let me summarize:

        Percentage of master or higher on Codeforces: <2%

        Percentage of IQ of people regarding of above two percnt: 130IQ +

        Mensa IQ acceptange: not under 130. Critical insihgt. Therefore 130+ IQ IS HIGH

        Hence I think the 123gjweq2's IQ argument is valid. Also, I think cheaters should not be allowed to post like this. please upvote I am a peaceful frog

          "Percentage of IQ of people regarding of above two percnt: 130IQ +"

          What does that mean?

          "Mensa IQ acceptange: not under 130. Critical insihgt. Therefore 130+ IQ IS HIGH"

          What does this mean? What is Mensa IQ percentage?

          "Also, I think cheaters should not be allowed to post like this."

          I haven't done a single contest, so why am I a cheater?

          Kinda confused

            it means. 2% of people have IQ over 130IQ or equal. 2% in codeforces is master.

            What does this mean? What is Mensa IQ percentage?

            Mensa IQ is prestigious IQ testing organization. Very prodigious to get accepted.

            I haven't done a single contest, so why am I a cheater?

                Okay, I have clear evidence.

                Lemma: having skips ≠ cheater. Proof for this is easy, legendary smart and wise tourist competiter also has skipped submissions.

                Therefore, we can take this: "having skips ≠ cheater."

                We take converse: "not having skips ≠ not cheater"

                We convert inequality sign to equality and negate left side: "not having skips = cheater"

                Therefore, this evidence shows: you are a cheater. Hence I suggest. To not fall in to this kind of proof: Please make some skipped submissions. Or have no submissions at all.

                  Your first statement: "having skips does not imply that you are a cheater" is not equivalent to your second statement: "not having skips does not imply you are not a cheater."

                  In correct. See:

                  Having skips does not imply one is cheater.

                  Having no skips does not imply one is not a cheater.

                  First statement refers to uncertainty of cheating coming if there is skips.

                  Second statement referse to uncertainty of cheating if there is not skips.

                  They are equivalent. Since: cheater can have skips or have not skips.

                  Furthermroe: take boolean logic.

                  if A ≠ B. Then !A ≠ !B. For example: A = true, B = false, A ≠ B, !A ≠ !B

                  True is have skips, false is have not skips.

                  True is cheater, false is not cheater. Such is the critical insight.

                  Let us see a similar claim:

                  Having earthquake does not imply having tsunami.

                  Now: not having earthquake does not imply not having tsunami.

                  Okay, they are equal. Because. If there be not an earthquake, there mey still be a tsunami. If there be an earthquake there may still eb a tsunami.

                  Irregardless, chance of tsunami exists. Hence, please accept this.

                  upvote please if eagree

                Correct, but. It is the first step to a proper proof.

                Indeed, correlation is not causation.

                However, I have made meager yet still valid steps to a proof that IQ and codefroces rating are connected.

                All you have done is criticize, make fun of, and joke, and have no evidence to the contrary. Please disprove that IQ and codefirces rating are independent factors.
