PROGRAM EXPLANATION
Algorithm and explanation
- Initialize the sample values used to classify a categorical feature.
- Process the data step by step using Categorical Naive Bayes.
- Display the result for classify a categorical feature and compare it with the documented sample output.
This example of classify a categorical feature processes the sample values in a controlled iteration. It demonstrates Categorical Naive Bayes and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST
Common mistakes
For classify a categorical feature, keep the data shape and value types consistent with Categorical Naive Bayes.
Keep every dependent statement inside the correct indented Python block.
Check denominators, numeric ranges and rounding before comparing the calculated value.
