Describe your change:

  • Add an algorithm?
  • Fix a bug or typo in an existing algorithm?
  • Add or change doctests? -- Note: Please avoid changing both code and tests in a single pull request.
  • Documentation change?

This pull request introduces a new logic_building_problems directory as discussed in issue #13501. It adds a collection of classic programming problems to help beginners practice core logic skills before tackling more complex data structures.

The added problems include various star patterns, number theory puzzles like Kaprekar's Constant, and simple interactive games. Since this PR establishes a new category, it contains multiple files.

Fixes #13501

Checklist:

  • I have read CONTRIBUTING.MD.
  • This pull request is all my own work -- I have not plagiarized.
  • I know that pull requests will not be merged if they fail the automated tests.
  • This PR only changes one algorithm file. To ease review, please open separate PRs for separate algorithms.
  • All new Python files are placed inside an existing directory.
  • All filenames are in all lowercase characters with no spaces or dashes.
  • All functions and variable names follow Python naming conventions.
  • All function parameters and return values are annotated with Python type hints.
  • All functions have doctests that pass the automated testing.
  • All new algorithms include at least one URL that points to Wikipedia or another similar explanation.
  • If this pull request resolves one or more open issues then the description above includes the issue number(s) with a closing keyword: "Fixes #ISSUE-NUMBER".
