Q. Write down a non recursive algorithm to traverse a binary tree in order.
Ans:
Non - recursive algorithm to traverse a binary tree in inorder is as follows:-
Initially in the beginning push NULL onto STACK and then set PTR = ROOT. Then repeat the steps written below until NULL is popped from STACK.
i. Continue down the left -most path rooted at PTR, pushing each node N onto STACK and stopping when a node N with no left child is pushed onto
STACK.
ii. [Backtracking.] Pop and process the nodes on
STACK. If the NULL is popped then Exit. If a node N
Having a right child R(N) is processed, set PTR = R(N) (by assigning PTR = RIGHT[PTR] and return to the Step(a)).
Q. The system allocates the memory for any of the multidimensional array from a big single dimensional array. Describe two mapping schemes that help us to store the two dimensi

How can we convert a graph into a tree ? Do we have any standardized algorithm for doing this?
Insertion & deletion of target key requires splaying of the tree. In case of insertion, the tree is splayed to find the target. If, target key is found out, then we have a duplicat

Determine the precondition of a binary search For instance, precondition of a binary search is that array searched is sorted however checking this precondition is so expensive
Explain th term input and output- Pseudocode Input and output indicated by the use of terms input number, print total, output total, print "result is" x and so on.
The space-complexity of the algorithm is a constant. It just needs space of three integers m, n and t. Thus, the space complexity is O(1). The time complexity based on the loop
