print leaf nodes of binary search tree

Leaf nodes of binary tree are the nodes with no children or no subtrees.
They have both left and right links as null.


In the above image nodes 1,4 ,7 ,13 have no sub-trees hence they are the leaf nodes.

Leaf nodes can be found easily by traversing the tree in inorder way and the printing the nodes that have no left or right subtrees.

Hashing with Quadratic Probing

Hashing is a technique used for storing , searching and removing elements in almost constant time. Hashing is done with help of a hash function that generates index for a given input, then this index can be used to search the elements, store an element, or remove that element from that index. A hash function is a function that is used to map the data elements to their position in the data structure used. For example if we use an array to store the integer elements then the hash function will generate position for each element so that searching, storing and removing operation on the array can be done in constant time that is independent of the number of elements in the array. For better look at the example below. now we face a problem if for 2 numbers same position is generated example consider elements 1 and 14 1 % 13 = 1 14 % 13 = 1 so when we get 1 we store it at the first position, but when we get 14 we see that the position 1 is already taken, this is a case of colli...
