Given an integer N representing the number of pairs of parentheses, the task is to generate all combinations of well-formed(balanced) parentheses.
Example 1:
Input:
N = 3
Output:
((()))
(()())
(())()
()(())
()()()
Example 2:
Input:
N = 1
Output:
()
Your Task:
You don't need to read input or print anything. Complete the function AllParenthesis() which takes Nas input parameter and returns the list of balanced parenthesis.
Expected Time Complexity: O(2N * N). Expected Auxiliary Space: O(2*N*X), X = Number of valid Parenthesis.
