Postorder traversal without recursion in c
WebPostorder traversal without a stack (or recursion, which is an implicit stack) just involves a lot of careful bookkeeping. It might be easier to understand using a simple but non-trivial example together with some diagrams of what's happening at each step of the algorithm. – Ted Hopp Sep 18, 2014 at 2:46 Add a comment Web5 Apr 2024 · Threaded Binary Tree Advantages: A linear traversal of the items in this Tree is possible. Since it does a linear traversal instead of using a stack, memory is conserved. …

Web8 Apr 2024 · Successful recursion requires branching at some point, a division of the code path into at least two cases, one of them the base case. Whether or not a return statement is required follows the same rule as that for non-recursive functions – a function that returns void is not required to have an explicit return statement.
