First install bazel environment,
change path of problem path = "problems/problems_2028/",
in BAZEL WORKSPACE, and try:
bazel test --cxxopt=-std=c++20 --test_timeout=3 --test_output=all //cpp:solution_test
or if you want to run more than one questions,
change problem and path in new_local_repository(name = "problem0", path = "problems/problems_1/"
in WORKSPACE and maybe add the name ref @problem0
in BUILD, and try:
bazel test --cxxopt=-std=c++20 --test_timeout=10 --test_output=all //cpp/tests:all
