How to solve problems - Codeforces
Usually, when people talk about this, they often say things like "try to view the problem as a graph problem" or "rephrase as a geometry problem (yuck!)" However, to become a Legendary Candidate Master like me, you need to multiply these pieces of advice together and divide by their greatest common divisor to realize that it's not enough to simply rephrase the problem -- you need to rephrase problem solving itself. Let's view problem solving as a graph, where one node represents the problem and another node represents the solution.

Practice is the only option to remove your if and else statement and write clean code. Check your friend's codeforces id and how many questions he has solved then you will get to know what it takes to remove multiple if else statements to a single line code. If you are new to competitive programming practice on hackerrank first and try to reach five star in problem solving. It will improve your basics and code quality. After that start practicing on codeforces, sort the questions rating wise first solve 50 problems 800 to 1000, 50 problems then 1000 to 1200... Don't forget to participate in the contest on codeforces. This is the only thing that shows your cp skill. And you can also check Atcoder for practice and participate in contests. I personally like atcoder contests more than codeforces. More on reddit.com

How to come up with the solutions: techniques - Codeforces
Such specific cases can be regarded as the simplifications of the problem, i.e. we can reason by the following principle: "if I don't know how to solve a complex problem, I think I'll simplify it and find the solutions of the simplified version". The popular examples of simplifications (specific cases): you get a problem for a tree. Consider its variant where the tree degenerates into a path; the problem has weights? Consider a variant where all the weights are equal either to one or to an arbitrary number, or there are only two distinct weights (and so on).

Search for "deliberate practice" on youtube. Apply that sports concept to Leetcode. Practice one topic/subtopic per week. Start with the easier problems first. Be sure to completely master a topic before you move on to the next one.

I'm personally inclined towards practicing random problems in your difficulty level until it becomes easier, as soon as it gets easier for you, then increase the difficulty. (i.e. you can sort problems by number of solves or by problem rating, and start from there) The issue with only practicing by topics/subtopics is that you get used to knowing the topics/hints upfront, but in real life you should be able to figure out that by yourself. Solving by topic might be useful when you encounter a weakness or an unfamiliar topic during your practice. Also, I recommend the codeforces catalog section, it has some advice from accomplished competitors.

Sometimes I have trouble with easy codeforces questions but the only way to do this is by practicing. I think you should start doing leetcode easy on some domain areas or do Hackerrank algorithms and solve all those domain areas first. Then jump into Codeforces. Another thing people have done is solve first classical 200 most solved SPOJ problems from easy to hard.

r/codeforces on Reddit: How do I gain the ability to solve the problems that I can't solve now?
March 19, 2024 -
I can solve 1100-level problems 70% of the time and 1200-level problems 40% of the time, and the rest of the time I fail to solve them and have to look at the editorial. I thought I would start solving 1200-level problems after I get to the point where I can solve any 1100-level problem very easily and quickly. Even though I am solving 1100-level problems almost every day, I feel like I am not improving.
So what should I do? Should I abandon the idea of getting good at the 1100-1200 range problems and then try to solve even harder problems, or should I just jump to 1500-1600 and try to solve them? Even if I fail to solve 1500-1600 problems, will just learning the solutions make it easy for me to solve lower difficulty problems?
My goal is to be able to solve Div. 2 A, B, C problems.
Problems I have solved so far:
800 - 84
900 - 31
1000 - 46
1100 - 42
1200 - 31

I can think of new ideas but they must be somewhat similar to the previous ones.
