Stack implementation using array

A stack is a data structure it serves as a collection of elements. It has 2 principle operation push and pop.
The push operation pushes the element on the top and the pop operation removes the element on the top. This can be seen in the below image.



Stack works on the principle of  Last In First Out or LIFO i.e the element that is entered last is removed first.
Stacks can be implemented using arrays as well as linked list.
There are a lot of applications of Stacks like
  • Recursion
  • Backtracking 
  • Memory management 
  • Activation records etc

The following program is to implement a stack using an array with maximum size of 20.

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...
