@DemondKing 4 года назад

That's cool, how did you learn cp and programming?

@sahilsharma2952 4 года назад

@@DemondKing I just like it so I keep on solving problems and read editorials. You just get the intuition along the way. I am just a beginner tho.

@DemondKing 4 года назад

@@sahilsharma2952 Can you tell me resources that you used?

@sahilsharma2952 4 года назад

@@DemondKing Participate in as many contests as you can. Read their editorials and read the new topics that you find. Alternatively if you wanna read all algos and DS first, try cp-algorithms.com and a2oj ladder problems for practice.

@LeandroCoutinho 4 года назад

what do you use Eclipse for? Debugging C++?

@UnwrapTheExperience 4 года назад

Can you please explain? .In the last question, why are you deleting the i,j because once you insert it and calculate all it's neighbor possible cases then it should get ignored as it is in tr2 and you have cleared tr1

@AIPlayerrrr 4 года назад

suggestion: plz briefly review the problem

@Learner010 4 года назад

when you add k on left hand side then why not you balance it by adding k on right hand side on the explanation of problem 2?

@paramgoswami7224 4 года назад

You dont know the k value so it will be hard to find the binary expression of n-30-k

@tmwilliamlin168 4 года назад

It's not the same equation

@yogeshpandey009 4 года назад

It is tricky to explain, basically 30 already includes 1s in k rows so he subtracts 1 for each k rows. n = 30 + (2^r_1 - 1 + 2^r_2 - 1 ..... + 2^r_k - 1) + k
