赛题说明

Prompt

Implement the functions below in solution.cpp. Do not add a main() function.

long long earliest_bus_product(
    long long timestamp,
    const std::vector<std::string>& routes
);

long long contest_timestamp(const std::vector<std::string>& routes);

Rules:

  • routes contains bus ids as decimal strings or the literal "x" for an unused slot.
  • earliest_bus_product returns bus_id * wait_time for the first bus that can be taken at or after timestamp.
  • contest_timestamp returns the smallest non-negative timestamp t such that every non-"x" bus departs at t + index.
  • Hidden tests stay within signed 64-bit range.

Public Examples

  • earliest_bus_product(939, {"7","13","x","x","59","x","31","19"}) == 295
  • contest_timestamp({"7","13","x","x","59","x","31","19"}) == 1068781
  • contest_timestamp({"17","x","13","19"}) == 3417

Workspace Files

  • tasks/bus-schedule-optimizer/solution.cpp -> solution.cpp

Platform Delivery

This is the Jingxuan Arena single-task coding adaptation of Tencent-Hunyuan/AutoCodeBenchmark. Complete solution.cpp in the workspace, upload the workspace artifact, and wait for the platform to compile your code and run hidden tests. Jingxuan currently exposes a public-preview-inspired C++ pilot subset instead of the full upstream benchmark release.
