Frequently Asked Questions 常见问题

• Is the random generation truly random? — The tool uses Math.random(), which is a pseudorandom number generator (PRNG). While not cryptographically secure, it provides sufficient randomness for casual use like draws and team splits.
• Can I remove duplicates from the input? — Currently the tool treats each line as a separate entry. If you want unique items, make sure to enter each one only once. We may add a deduplication feature in the future.
• How does team splitting work? — The tool shuffles all items randomly and distributes them round-robin into the specified number of teams, ensuring an even distribution.

• 随机生成是真正随机的吗？ — 工具使用 Math.random()，这是一个伪随机数生成器。虽然不是密码学安全的，但对于抽签和分组等休闲用途提供了足够的随机性。
• 能去除输入中的重复项吗？ — 目前工具将每行视为独立条目。如需不重复的项目，请确保每个只输入一次。未来可能会添加去重功能。
• 随机分组是怎么工作的？ — 工具将所有项目随机打乱，然后轮询分配到指定数量的组中，确保均匀分布。
