…与否
whether or not
Structure
动词／形容词 与否 ， … ； … 取决于／关系到 动词 与否
What it means
A written way to say “whether or not”: X与否 turns a yes-or-no question into a noun phrase, the same as 是否X or X不X.
How it is built
Verb/adjective + 与否, as a topic or after 取决于, 关系到, 在于, 不论: 成功与否，关键在于落实 (Whether it succeeds depends on carrying it out).
When to use it
Formal writing: reports, rules, commentary. 是否 says the same but goes before the verb. In speech say X不X: 离不离婚, 成不成功.
Watch out
与否 always follows the verb, and never doubles with 是否. ✗与否离婚 ✗是否离婚与否 ✓离婚与否，由双方自己决定。
Examples

Whether to divorce or not is for the couple themselves to decide; no one else has the right to interfere.
