<p>Data structures and Algorithms are one of the most important aspects of software development and enginering which every programmer should know. Data structure is a particular way of storing and organizing data in a computer so that it can be used efficiently. A data structure is a special format for organizing and storing data. General data structure types include arrays, files, linked lists, stacks, queues, trees, graphs. data structures are classified into two types:Linear data structures: Elements are accessed in a sequential order but it is not compulsory to store all elements sequentially. Examples: Linked Lists, Stacks and Queues. Non linear data structures: Elements of this data structure are stored/accessed in a non-linear order. Examples: Trees and graphs.<br> <br> <img src="/img/data.jpg" alt="html"

<p style="color:red">image showing types of data structures</p>
<p>Characteriatics OF Data Structures (Advantages)<p></p>(1)Array: Quick insertion, very fast access if index known</p> <p>(2)Ordered array:Quicker search than unsorted array.</p><p>(3)Stack:Provides last-in,first-out access.</p> <p>(4)Queue:Provides first-in,first-out access.</p> <p>(5)Linked list:Quick insertion, quick deletion.</p> <p>(6)Binary tree:Quick search, insertion ,deletion (if tree remains balanced).</p> <p>(7)Red-black tree:Quick search, insertion,deletion. Tree always balanced.</p><p>(8)2-3-4 tree:Quick search, insertion,deletion. Tree always balanced. Similar trees good for disk storage.</p> <p>(9)Hash table:Very fast access if key known. Fast insertion.</p><p>(10)Heap:Fast insertion, deletion, access to largest item.</p><br><br> <p> Characteriatics OF Data Structures (Disadvantages)</p> <p>(1)Array:Slow search, slow deletion, fixed size.</p>
<p>(2)Ordered array:Slow insertion and deletion, fixed size.</p> <p>(3)Stack:Slow access to other items.</p><p>(4)Queue:Slow access to other items.</p> <p>(5)Linked list:Slow search.</p> <p>(6)Binary tree:Deletion algorithm is complex.</p> <p>(7)Red-black tree:Complex.</p> <p>(8)2-3-4 tree:Complex.</p> <p>(9)Hash table:Slow deletion, access slow if key not known,inefficient memory usage.</p> <p>(10)Heap:Slow access to other,items.</p>

<p>Algorithms</p>
<p>An algorithm can be thought of as the detailed instructions for carrying out some operation.In a computer program these instructions take the form of program statements.The concept of recursion is important in designing certain algorithms. Recursion
involves a function calling itself.</p>

<p>Google dorks are strings used for looking vulnerable websites on the web. Google Dorking, is a computer hacking technique that uses Google Search and other Google applications to find security holes in the configuration and computer code that websites use </p>
