Approach 1: To form all the sequences of balanced bracket subsequences with n pairs. Are you sure you want to create this branch? This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Whenever you hit a closing bracket, search if the top of the stack is the opening bracket of the same nature. The idea is to put all the opening brackets in the stack. You signed in with another tab or window. A tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. So the subsequence will be of length 2*n. There is a simple idea, the ith character can be { if and only if the count of { till ith is less than n and ith character can be } if and only if the count of { is greater than the count of } till index i. Every close bracket has a corresponding open bracket of the . Only when left and right both equal to 0, the string s will be push into answer vector.
