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_number(long long n);

Return a map with exactly these keys:

  • original_number
  • digit_count_recursive
  • digit_count_iterative
  • digit_count_log
  • is_negative
  • is_even

Rules:

  • Digit counting ignores the sign of the input.
  • 0 has a digit count of 1.
  • The three digit-count fields must always agree.
  • Use 1 for true and 0 for false in is_negative and is_even.

Public Examples

  • Input: 0 Output:

    • original_number = 0
    • digit_count_recursive = 1
    • digit_count_iterative = 1
    • digit_count_log = 1
    • is_negative = 0
    • is_even = 1

  • Input: -12034 Output:

    • original_number = -12034
    • digit_count_recursive = 5
    • digit_count_iterative = 5
    • digit_count_log = 5
    • is_negative = 1
    • is_even = 1

Workspace Files

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.
