By bansalarpan4, history, 5 months ago, In English

hlo , i m new to competitive programming . i have seen many pro competitive coders using sublime text (with input.txt , output.txt and error.txt files ) as in https://www.youtube.com/watch?v=r-ZoM2ex-uk&list=PLAj_13N2fk-SkD-A1cDAs-QpHGQcdnzoB&index=4

this setup really looks nice and useful does anyone know the steps to be taken o any tutorial for this set up ??

just make 2 files = inputf.in , outputf.in and main file to write code then in build system paste { "cmd" : ["g++ -std=c++17 $file_name -o $file_base_name && timeout 4s ./$file_base_name<inputf.in>outputf.in"], "selector" : "source.c", "shell":true, "working_dir" : "$file_path" }

    It's a random number generater, constructed with seed chrono::steady_clock::now().time_since_epoch().count() . Random numbers are needed when we want to hash a string, and we need a seed changing rapidly by time to ensure it's randomness, otherwise the hash method can be easily hacked, just as what I'm doing these days on problem 1984D.

        I think it's just used in string suffix structure problems, and is only useful in this kind of problem to prevent hacking. But you may see this in other problems' codes because some people just write this into their templates.

I used this to configure it (for Linux, but is similar to Windows). As a build system I use this:

Use Notepad++ and all your problems will go away...
