Setting up the system environment

Make yourself familiar with the environment at the exam center. Mock exam page is available here: https://www.codechef.com/ICO20MCK. During the contest, when you submit the code, it will be evaluated against some test data files. These test data files will also be available for you to download and use on your system. The main purpose behind this is to reduce the negative effect of rare unfortunate events like the internet connection going down for a while in some center. In such scenarios, it'll be beneficial for you to know how to test your code locally using the command line. You can learn the basics of that, here. You can also use it to debug your code, if you are comfortable with it.

The following compilers and IDEs will be provided locally.

Language Compiler IDE
C/C++ gcc6.3 with support for C++14 Code::Blocks or CLion
Java Oracle Java 8 Eclipse or IntelliJ Community Edition
Python Python 2.7,Python 3.5 PyCharm Community Edition

Sublime text and gedit will be provided as text editors.
