Hello everyone,

I'm not a good English writer and i hope you understand me.

For the last 3 days i was thinking why i didn't solve a specific problem in a running round and some people with same rank as me solved it.

Lets go ahead to the result of thinking :

1.they are smarter than me (i have nothing to do with talent).

2.they solved more problems than me or a specific problems that helped them to solve the problem that i couldn't solve (let's try hard work beat talent).

So i developed a PHP script to get me the top common problems from the top 10 users in a specific round i participated in it with same rank as me (Problems i didn't solve)

You can use the script here hunterscript.com

For example i used the script to generate a sheet of problems as tourist in the last round he participate in.

you can check result here

Due to the limited resources for the host (512 ram and 100 process only).

generating the report will take about 5 minute or maybe more if there is long queue(every report go to queue)

if you faced any issue feel free to contact me

i hope this script helps you.

repository at Github

Change log :-

  1. Fix issue that prevent handles with dots or other special characters from making report.
  2. Adding confirmation before requesting the report (by shakil.ahamed)

First i have an issue and i really need your help. issue is i recently joined competitive programing and i tried to join many Codeforces rounds but every time i lose rate and i searched for the main reason why i lose rate .

It's because every round i start with A and when i try to think for solution my brain gives me a hard one even for simple problem so i lose time and cant get a solution.

So. Can you guys tell me some tips to think about solution for Div2 A,B,C Ex. as i saw most of C problems need data structure most of A problems focus on Implementation

E.x sometime i can think for graph solution when the problem need a simple brute force
