int key1 = rand.nextInt();
        // flip input bit for key2
        int key2 = key1 ^ (1 << i);
        // get hashes
        int hash1 = function.hashInt(key1).asInt();
        int hash2 = function.hashInt(key2).asInt();
        // test whether the hash values have same output bits
        same |= ~(hash1 ^ hash2);
        // test whether the hash values have different output bits
        diff |= hash1 ^ hash2;

6. **Testing**:
   - Assume the submitter tested the code. If testing is unclear, ask for details (e.g., “How was this tested?”).
   - Reject untested PRs unless testing is infeasible, then assist with test setup.

## Tips for Success

- **Small PRs**: Easier to review, faster to merge. Split large changes logically.
- **Clear Commits**: Use `git rebase -i` to refine history before submitting.
