iphelf / CodeforcesStarterPack

This is a CMake project base for solving programming exercises (e.g. Codeforces).

Monorepo for programming exercises

Usage

Coding

Code under source directory.

Test your code against the test case (in.txt and oracle.txt) with CTest:

ctest --output-on-failure

or, use tool/tester.py directly:

./tool/tester.py <executable> <input file> <oracle file>

or, directly use the executable produced by CMake, e.g. like this:

./build/Codeforces < ./source/in.txt

Managing

Manage your code with this directory structure:

• source: current working code
• template: template code
• archive: history code

And use tool/archiver.py to automate operations:

# To backup `source` to `archive`:
./tool/archiver.py backup

# To restore from some directory under `archive`:
./tool/archiver.py restore

# To reset `source` with `template`
./tool/archiver.py reset

# To backup `source` to `archive` and then reset `source` with `template`
./tool/archiver.py archive

Note: use archiver.ini or command line arguments to specify paths.

Example

Here is the process of a typical use case:

1. Set archive=archive/Codeforces/E136 in archive.ini
2. For each problem P in {A, B, C, D}:
   1. Copy sample input and output to source/in.txt and source/oracle.txt
   2. Solve the problem in source/main.cpp
   3. Archive source to a subdirectory under archive/Codeforces/E136/ by ./tool/archiver.py archive (the tool will interactively ask for the problem ID, and use it to name the subdirectory)
