Here is some code for finding cycles in a dependency graph: https://github.com/citronella3alain/CoNLL-U_cycles

The original task was here: https://codein.withgoogle.com/dashboard/task-instances/6636420875681792/

Fix the errors:

• parse the conllu format,
• provide an example of a graph with a cycle and one without a cycle.
• report cycles in terms of sequences of nodes

Optionally rewrite the algorithm in JavaScript.
