Generate Parentheses
Given n pairs of parentheses Generate all combinations of well-formed parentheses Example: n = 3 => ["((()))","(()())","(())()","()(())","()()()"]
Generate Parentheses is a dynamic programming question: define the state cleanly and the transitions usually follow. Interviewers love it because it reveals your state-and-transition thinking and your edge-case discipline. The trap is picking a state that's too vague; keep it minimal and consistent.
