**I want to post o series of tutorial on data structure. I think it is useful for programming contest.**
Please comment if u find any error.

**Overview**

Data structure is a particular way of storing and organizing data. Data structure provide a means to manage to large amount of data efficiently for uses such as large database and internet services . There can be many ways to organize the same data and sometimes one way is better than the others in some contexts.

**Operations of data structure**

We can also perform some operation on data structure such as insertion(addition), deletion(remove), searching(locate). sorting(arranging), merging(combining) etc.

**Types**

There are two types of data structures. such as :

```
1. Linear data structure : A data structure that traverses the data elements sequencially. Example : array, linkedlist, stack, queue etc .
2. Non linear data structure : A data structure that traverses the data elements dynamically. Example :tree, graph etc .
```

**Algorithm**

Algorithm is a list of instruction that can be followed to perform a task. To write an algorithm we do strictly follow grammar of any particular language may be near to a programming language.

**Complexity of Algorithm**
It is a function which measure the time and/or space used by an algorithm. There are two types of complexities such as

```
1. Time complexity : This complexity is related to execution time of an algorithm. It depends on the number of elements comparition and number of elements movements.
2. Space complexity : Space complexity is related to space needs in main memory for the data used to implement the algorithm.
```

N.B Please wait for next tutorial.
