program creation of a linked listin the next example wewill look to the process of addition of new nodes to the list with the function
program will demonstrate deletion of an element from the linear array declaration of deletelist function voiddeletelistlist int definition of
to delete an element in the list at the end we can delete it without any difficult but assume if we desire to delete the element at the straining or
program will demonstrate the insertion of an element at desired position inserting an element into contiguous list linear array at particular
in the array implementation of lists elements are stored into continuous locations in order to add an element into the list at the end we can insert
in the array implementation of the lists we will use the array to hold the entries and a separate counter to keep track of the number of positions
it is a useful tool for indicating the logical properties of data type it is a collection of values amp a set of operations on those values
in the earlier unit we have discussed about the arrays arrays are data structures of fixed size insertion amp deletion involves reshuffling of array
for avl trees the deletion algorithm is a little more complicated as there are various extra steps involved in the deletion of node if the node is
initially nodes are inserted in an avl tree in the same manner as an ordinary binary search treethough the insertion algorithm for any avl tree
a binary search tree is binary tree which is either empty or a node having a key value left child amp right childby analyzing the above definition we
linked list representations contain great advantages of flexibility on the contiguous representation of data structures however they contain few
tree is a widely used data structure employed for representing several problems we studied tree like a special case of acyclic graph though rooted
for preorder traversal in the worst case the stack will rise to size n2 where n refer to number of nodes in the tree another method of traversing
as we have seen as the traversal mechanisms were intrinsically recursive the implementation was also easy through a recursive procedure though in the

there are three typical ways of recursively traversing a binary tree in each of these the left sub-trees amp right sub-trees are visited recursively
we have discussed already about three tree traversal methods in the earlier section on general tree the similar three different ways to do the

full binary trees a binary tree of height h that had 2h -1 elements is called a full binary treecomplete binary trees a binary tree whereby if the
a binary tree is a special tree where each non-leaf node can have atmost two child nodes most important types of trees which are used to model yesno
there are three kinds of tree traversals namely postorder preorder and inorderpreorder traversal each of nodes is visited before its children are
tree is dynamic data structures trees can expand amp contract as the program executes and are implemented via pointers a tree deallocates memory
this is a k-ary position tree wherein all levels are filled from left to right there are a number of specialized treesthey are binary trees avl-trees
