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)).

If a Dequeue is implemented via arrays, then this will suffer with the similar problems which a linear queue had suffered. Program 8 gives the array implementation of Dequeue.

Ans. An algorithm for the quick sort is as follows: void quicksort ( int a[ ], int lower, int upper ) { int i ; if ( upper > lower ) { i = split ( a, lower, up
Q. The degree of a node is defined as the number of children it has. Shear show that in any binary tree, the total number of leaves is one more than the number of nodes of degree 2
