WebIdea : To generate all the valid strings containing balanced parenthesis, we use a recursive algorithm. This algorithm keeps track of the number of opening and a closing parenthesis that are added to the string. If the sum of an opening and a closing parenthesis is the same as the length of the string, we print the generated string, Else … WebJul 18, 2024 · Solution Steps.

WebA legal sequence of parentheses is one in which the parentheses can be properly matched (each opening parenthesis should be matched to a closing one that lies further to its right). For instance, () ( ()) is a legal sequence of parentheses. I should calculate the number of legal sequences of length 2 n. The answer is C n = ( 2 n n) − ( 2 n n ...
