PROGRAM EXPLANATION
Algorithm and explanation
- Import the required standard-library tools and prepare the sample data for assign a point to a centroid.
- Apply K-means and Cluster assignment to compute the required result.
- Display the result for assign a point to a centroid and compare it with the documented sample output.
This example of assign a point to a centroid computes the result directly from the prepared sample data. It demonstrates K-means and Cluster assignment and prints a deterministic result that can be checked against the sample output.

Common mistakes
For assign a point to a centroid, keep the data shape and value types consistent with K-means.
Apply K-means in the same order shown by the algorithm; changing the order can change the result.
Verify the final K-means and Cluster assignment result against the sample before trying new data.
