Lowest Common Ancestor of nodes in BST

This post is about finding the lowest common ancestor of 2 nodes in a binary search tree.

Lowest Common Ancestor of 2 nodes x and y is the node that has both x and y as its desendents. The below image is might help you to understand the above statement.

In this tree, the lowest common ancestor of the nodes x and yis marked in dark green. Other common ancestors are shown in light green.

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...
