C DSA
PROGRAM EXPLANATION
Algorithm and explanation
- Initialize the sample values used to use an iterator explicitly.
- Apply iter() and next() to compute the required result.
- Display the result for use an iterator explicitly and compare it with the documented sample output.
This example of use an iterator explicitly computes the result directly from the prepared sample data. It demonstrates iter() and next() and prints a deterministic result that can be checked against the sample output.

DEBUGGING CHECKLIST
Common mistakes
For use an iterator explicitly, keep the data shape and value types consistent with iter().
Apply iter() in the same order shown by the algorithm; changing the order can change the result.
Verify the final iter() and next() result against the sample before trying new data.
