Generate parentheses

CodingAlgorithms & data structuresMid–Senior~20 min

Generate all well-formed strings of n pairs of parentheses. Return them sorted lexicographically. For n = 0 return a list containing the single empty string. 0 <= n <= 8.

Implement
generate_parentheses(n: int) → list[str]
Examples
in[3]out["((()))","(()())","(())()","()(())","()()()"]
