Almost left half of the Internet users across the globe use ADSL routers/modems to connect to the Internet. However, most of them are unaware of the fact that it has a serious vulnerability in it which can easily be exploited by anyone with a basic knowledge of computer. In this post, I will show you how to hack an Ethernet … Read more
How to Add a New User in Linux To add/create a new user, all you’ve to follow the command ‘useradd‘ or ‘adduser‘ with ‘username’. The ‘username’ is a user login name, that is used by user to login into the system. [root@centos ~]# useradd centos When we add a new user in Linux with … Read more
Two dimensional arrays are also called table or matrix, two dimensional arrays have two subscripts Two dimensional array in which elements are stored column by column is called as column major matrix Two dimensional array in which elements are stored row by row is called as row major matrix First subscript denotes number of rows … Read more
Simplest data structure that makes use of computed address to locate its elements is the one-dimensional array or vector;number of memory locations is sequentially allocated to the vector. A vector size is fixed and therefore requires a fixed number of memory locations. Vector A with subscript lower bound of “one” is represented as below L0is … Read more
Worst Case Analysis In the worst case analysis, we calculate upper bound on running time of an algorithm. We must know the case that causes maximum number of operations to be executed. For Linear Search, the worst case happens when the element to be searched is not present in the array. When x is not … Read more
Algorithm An essential aspect to data structures is algorithms. Data structures are implemented using algorithms. An algorithm is a procedure that you can write as a C function or program, or any other language. An algorithm states explicitly how the data will be manipulated. Algorithm Efficiency Some algorithms are more efficient than others. We would … Read more
Design of efficient data structure must take operations to be performed on the data structures into account. The most commonly used operations on data structure are broadly categorized into following types, Create The create operation results in reserving memory for program elements. This can be done by declaration statement. Creation of data structure may take … Read more
Data Structures are normally classified into two broad categories. 1.Primitive Data Structure 2.Non-primitive data Structure Data types A particular kind of data item, as defined by the values it can take, the programming language used, or the operations that can be performed on it. Primitive Data Structure Primitive data structures are basic structures and are … Read more
