Write the non-recursive algorithm to traverse a tree in preorder.
The Non- Recursive algorithm for preorder traversal is as follows:
Initially push NULL onto stack and then set PTR=Root. Repeat the steps until PTR= NULL.
1. Preorder down the left most path routed at PTR.
2. Processing every node N on the path and pushing every right child if any onto the stack.[The traversing stops when (PTR)=NULL]
3. Backtracking: pop and assign to PTR the top element on stack. If PTR not equal to NULL then return to step 1 or else exit.
Retrieval of information is made simpler when it is stored into some predefined order. Therefore, Sorting is a very important computer application activity. Several sorting algorit

Threaded Binary Tree : If a node in a binary tree is not having left or right child or it is a leaf node then that absence of child node is shown by the null pointers. The spac
Q. Draw the expression tree of the infix expression written below and then convert it intoPrefix and Postfix expressions. ((a + b) + c * (d + e) + f )* (g + h )
As we have seen, as the traversal mechanisms were intrinsically recursive, the implementation was also easy through a recursive procedure. Though, in the case of a non-recursive me
Determine the importance of array Arrays are significant since they allow many values to be stored in a single data structure whereas providing very fast access to each value.
Post-order Traversal This can be done both iteratively and recursively. The iterative solution would need a change of the in-order traversal algorithm.

What do you mean by hashing? Hashing gives the direct access of record from the file no matter where the record is in the file. This is possible with the help of a hashing func
