PROGRAM EXPLANATION
Algorithm and explanation
- Initialize the sample values used to update a state value.
- Apply Value iteration and Bellman equation to compute the required result.
- Display the result for update a state value and compare it with the documented sample output.
This example of update a state value computes the result directly from the prepared sample data. It demonstrates Value iteration and Bellman equation and prints a deterministic result that can be checked against the sample output.

Common mistakes
For update a state value, keep the data shape and value types consistent with Value iteration.
Apply Value iteration in the same order shown by the algorithm; changing the order can change the result.
Verify the final Value iteration and Bellman equation result against the sample before trying new data.
