You are given a positive integer N. You have to generate all possible sequences of balanced parentheses using N pairs of parentheses. A sequence of brackets is called balanced if one can turn it into a valid math expression by adding characters ‘+’ and ‘1’. Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time. Check Balanced Parentheses in an Expression using Stack – Java Code.

If the current character is an opening bracket ( or { or [ then push it to stack. If the current character is a closing bracket ) or } or ] then pop from stack and if the popped character is the matching starting bracket then fine At the end of the traversal, if there is some opening bracket left in stack then the string is "not balanced". Count pairs of parentheses sequences such that parentheses are balanced in C++ C++ Server Side Programming Programming We are given a string containing the parentheses and the task is to calculate the count of pairs of parentheses sequences that can be formed such that the parentheses are balanced. Balanced parentheses means that each opening symbol has a corresponding closing symbol and the pairs of parentheses are properly nested. Consider the … Balanced parentheses means that each opening symbol has a corresponding closing symbol and the pairs of parentheses are properly nested. Consider the … The expression can contain the following parentheses →’ (’, ‘)’, ‘ {‘, ‘}’, ‘ [‘, ‘]’. The expression is said to be balanced if: The order of the opening and closing brackets is same.

If the current character is a closing bracket (‘)’ or ‘}’ or ‘]’) then pop from stack and if the popped character is the matching starting bracket then fine else brackets are not balanced. Lisp is notorious for using lots and lots of parentheses.
