EXPECTED OUTPUT FOR THE SAMPLE
B {'A': 8, 'B': 6, 'C': 8}PROGRAM EXPLANATION
Algorithm and explanation
- Initialize the sample values used to calculate an a-star priority.
- Process the data step by step using A* and Cost.
- Display the result for calculate an a-star priority and compare it with the documented sample output.
This example of calculate an a-star priority processes the sample values in a controlled iteration. It demonstrates A*, Cost, and Heuristic and prints a deterministic result that can be checked against the sample output.

Common mistakes
For calculate an a-star priority, keep the data shape and value types consistent with A*.
Keep every dependent statement inside the correct indented Python block.
Verify the final A* and Cost result against the sample before trying new data.
