PROGRAM EXPLANATION

Algorithm and explanation

Initialize the sample values used to choose the next token greedily.
Apply Greedy decoding and Token probability to compute the required result.
Display the result for choose the next token greedily and compare it with the documented sample output.

This example of choose the next token greedily computes the result directly from the prepared sample data. It demonstrates Greedy decoding and Token probability and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST

Common mistakes

Check this

For choose the next token greedily, keep the data shape and value types consistent with Greedy decoding.

Check this

Apply Greedy decoding in the same order shown by the algorithm; changing the order can change the result.

Check this

Verify the final Greedy decoding and Token probability 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.
