Collect examples

Description / 説明

We want to add more Python scripts to examples/ directory. They are used for testing ($ python3 scripts/integration_tests.py).

examples/ の中に置いてある Python スクリプトは自動で実行されてテストに使われますが、これをもっと増やしたい。
日々のコンテストのついでにコツコツに追加したり、ABC の B, C あたりをまとめて Python で解いて examples/ に追加するのをしないとだめそう。

How to add a script and test cases / スクリプトとテストケース追加の手順

1. optional: Run $ python3 scripts/add_test_cases.py URL
   • example: $ python3 scripts/add_test_cases.py https://atcoder.jp/contests/abc123_a
   • This makes template files like examples/abc123_a.py examples/data/abc123_a.sample-1.in examples/data/abc123_a.sample-1.out examples/data/abc123_a.large.generator.py examples/data/abc123_a.solver.cpp.
2. Write a Python script (e.g. examples/abc123_a.py) which Jikka processes
3. Write a generator of input cases (e.g. examples/data/abc123_a.large.generator.py) and an expected solution (e.g. examples/data/abc123_a.solver.cpp)
   • When you add another script for a problem which already has test cases, please edit examples/data/METADATA.json instead.
   • When you use a problem of Library Checker or Jikka Judge, please edit examples/data/METADATA.json instead.
   • optional: When you write a Python script for a non-existing problem, please consider adding it to Jikka Judge.
   • You can use Python instead for expected solutions. Delete examples/data/abc123_a.solver.cpp and create examples/data/abc123_a.solver.py
   • When the generated C++ code gets WA, move the Python script and test cases to examples/wip/. You can skip making test cases.
   • When the generated C++ code gets TLE, move the Python script to examples/wip/tle/. Scripts under examples/wip/tle/ still used to check non-WA.
4. optional: add more test cases like examples/data/abc123_a.hand-1.in examples/data/abc123_a.hand-1.out
5. optional: Update examples/README.md

Motivation / 動機

Testing is important.
