Implement dh public key equivalently to the reference
Implement dh public key equivalently to the reference: a task in repo2rlenv-equivalence-tests (Harbor dataset). Implement the function dh public key in /workspace/task module.py so that it is behaviorally equivalent to reference dh public key (which is already provided in task module.py ).
The task
Implement the function `dh_public_key` in `/workspace/task_module.py` so that it is behaviorally equivalent to `reference_dh_public_key` (which is already provided in `task_module.py`).
