Imported from Tencent-Hunyuan/AutoCodeBenchmark public preview and adapted as a Jingxuan Arena C++ pilot task. Complete solution.cpp in the local workspace and upload the workspace artifact for hidden-test grading.

Task Brief

Prompt

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

std::map<std::string, long long> analyze_text(const std::string& input);

Return a map with exactly these keys:

  • length
  • uppercase
  • lowercase
  • vowels
  • consonants
  • digits
  • spaces
  • special_chars

Rules:

  • Treat A/E/I/O/U and their lowercase forms as vowels.
  • Count ASCII alphabetic letters that are not vowels as consonants.
  • spaces counts all whitespace characters accepted by std::isspace.
  • special_chars counts everything that is neither alphanumeric nor whitespace.

Public Examples

  • Input: Hello World! 123 Output:
    • length = 16
    • uppercase = 2
    • lowercase = 8
    • vowels = 3
    • consonants = 7
    • digits = 3
    • spaces = 2
    • special_chars = 1

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.
