PROGRAM EXPLANATION

Algorithm and explanation

Initialize the sample values used to use weighted model voting.
Process the data step by step using Weighted voting.
Display the result for use weighted model voting and compare it with the documented sample output.

This example of use weighted model voting processes the sample values in a controlled iteration. It demonstrates Weighted voting and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For use weighted model voting, keep the data shape and value types consistent with Weighted voting.

Check this

Keep every dependent statement inside the correct indented Python block.

Check this

Verify the final Weighted voting result against the sample before trying new data.

Try it yourself

Practice: Run the program with the sample input, predict its output, and then test one boundary case of your own.
