The recursive function is run once for each of the n n n nodes, and the body of the recursive function is O (1) O(1) O (1).Therefore, this gives a total of O (n) O(n) O (n).. Space complexity : O (n) O(n) O (n), where n n n is the number of nodes in the Linked Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Even better, if A is a subset of B then the number representing A is less than that representing B, which is convenient for some dynamic programming solutions.
