EXPECTED OUTPUT FOR THE SAMPLE
('B', 2)PROGRAM EXPLANATION
Algorithm and explanation
- Initialize the sample values used to select a uniform-cost frontier node.
- Apply Uniform-cost search and Path cost to compute the required result.
- Display the result for select a uniform-cost frontier node and compare it with the documented sample output.
This example of select a uniform-cost frontier node computes the result directly from the prepared sample data. It demonstrates Uniform-cost search and Path cost and prints a deterministic result that can be checked against the sample output.

Common mistakes
For select a uniform-cost frontier node, keep the data shape and value types consistent with Uniform-cost search.
Apply Uniform-cost search in the same order shown by the algorithm; changing the order can change the result.
Verify the final Uniform-cost search and Path cost result against the sample before trying new data.
