PROGRAM EXPLANATION

Algorithm and explanation

Import the required standard-library tools and prepare the sample data for calculate a scaled attention score.
Process the data step by step using Attention and Scaled dot product.
Display the result for calculate a scaled attention score and compare it with the documented sample output.

This example of calculate a scaled attention score processes the sample values in a controlled iteration. It demonstrates Attention and Scaled dot product and prints a deterministic result that can be checked against the sample output.
