PROGRAM EXPLANATION
Algorithm and explanation
- Initialize the sample values used to multiply matrices.
- Process the data step by step using Matrix multiplication.
- Display the result for multiply matrices and compare it with the documented sample output.
This example of multiply matrices processes the sample values in a controlled iteration. It demonstrates Matrix multiplication and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST
Common mistakes
For multiply matrices, keep the data shape and value types consistent with Matrix multiplication.
Keep every dependent statement inside the correct indented Python block.
Verify the final Matrix multiplication result against the sample before trying new data.
