This is for boosting the speed and have good commonds with the tricky implementations

There are many Div. 3 will come and I will also try my best to keep this blog update.

Although if you want to generate these links at any time locally you can find the code on my GitHub repo: https://github.com/adshin21/Codeforces-Contest-Selector-By-Div-s

So I've collected the links for all the Div. 3's that has happened.

Fast Coding

Updated at May 3rd , 2020

I saw on Codeforces on a regular basis, that there are a lot of questions and answers about practicing and practicing more.

Although It is my opinion that the Educationals Rounds are best for this, at least for people like me. They learn from it and the problems are very nice and interesting.

PS: I do not know how to place that table in the center.
If any links are broken or having some issue let me know in the comments. Happy Coding :)

I'm a python programmer and I genrally happens that some problem on CF does not have any submission in Python, it is either Python 2 or Python 3 but ...

This problem that needs simple dfs ( sorry for spoiler but right now I'm not asking for help in solution ) gives Run Time Error on test 15.

After failing to get several times on this problem , I went for the accepted submissions then I found most of them having same result as mine ( Run Time Error on test 15 ) and there is no Accepted solutions in Python.

I'm here to ask may someone correct or find the error why it is getting RE or tell me the exact reason.

My code

Although this problem is from Educational Round 1.

I don't know at that time CF allows submissions in python or not. Somehow I managed to get AC using C++.

Sorry for my poor english. Thank You.

As I was solving this problem where I have to find the min of something with ans.

In my machine it showed the correct ans where I'd defined ans = sys.maxsize

I was getting wrong answer every time. My submission

Just changed sys.maxsize to 10^18 and got AC. Link

I used this algorithm Link

I just want to ask why they are using 32 bit interpreter.

P.S. — I didn't have any personal issue with that but I came to know my fault after the contest had been finished.

Sorry for my poor english. :)

My solution in Python3... Link 1

My Solution in PYPY3... Link 2

Any suggestion will be also great.

Thank You !
