Problem statements and solutions for the 2020 Coding Battle, hosted by Le Shaker, a programming contest designed and written by INSAlgo, a student union from INSA Lyon.
- Pre Coding Battle (statements only available in french for now)
- Coding Battle
The solutions available are the ones we wrote and solutions from contributors that we approved. There are often many ways to solve a problem. Our solutions are not perfect but adapted to the skills we wanted to evaluate at each task. Please feel free to add the solutions for the missing languages, or better solutions than the ones we did, by forking this repository and submitting a pull request. Add your solution under the sol/ folder in the problem directory. Add your name on the first line as a comment
If you translate an existing solution in a new language, please try to follow the structure, naming conventions and comments of the existing solution. Thanks for contributing :)
We won't reopen the platform, because it is costly to host and you can test your solutions locally or import the contest on your own platform.
To test your solutions, you can use piping in a terminal. For example, on Linux (if you don't use a Unix shell, you can find tutorials online):
# Python
python solution.py < ../input/input0.txt
# C++
./sol < ../input/input0.txt
# JavaScript
js sol.js < ../input/input0.txt
# etcWe also provide a way to automatically run your script against the solutions : test_solution.sh and test_all_solutions.sh.
Usage : ./test_solution.sh <path_to_solution>. Supported languages : Python 3, Python 2, C, C++, Rust, Haskell, Java, Elixir, Groovy. You must have the language interpreter/compiler installed in order for the script to work.
Because it can run unverified programs, use this script at your own risk.
We read a lot of your submissions in the last few contests, and received many questions. Here is some advice if you want to avoid common mistakes:
- Learn to manage input / output. You can't afford to lose time on something like that when doing competitive programming. Most of the contests have the same format of input and output: reading space-separated lists of integers, strings, floats, or read multiple lines.
- Read carefully the format of input and output: a typo can ruin your solution.
- You don't have to check that the input is within the given bounds. The input is within the given bounds. Otherwise, why would we even provide the bounds?
