海外TECH	DEV Community	Introduction to Data structures and algorithms	https://dev.to/dumboprogrammer/introduction-to-data-structures-and-algorithms-6pj	Introduction to Data structures and algorithmsI wanted to make this tutorial as beginner friendly as possible If you didn t understand something feel free to ask me in the comments I will reply I will use c and c for this tutorial as it gives much more access and you actually know what you are doing So I expect you to know the basics of this languages respectively I wrote a blog of C you can read that Let s clear up our basics with these terms before deep diving into DSA Data Structures and Algorithms are two different things Data Structures These are like the ingredients you need to build efficient algorithms These are the ways to arrange data so that they data items can be used efficiently in the main memory Ex Array Stack Linked List and many more Algorithms Sequence of steps performed on the data using efficient data structures to solve a given problem be it a basic or real life based one Ex sorting an array Some other Important terminologies Database Collection of information in permanent storage for faster retrieval and updation Examples MySql MongoDB etc Data warehouse Management of huge data of legacy data the data we keep at a different place from our fresh data in the database to make the process of retrieval and updation fast for better analysis Big data Analysis of too large or complex data which cannot be dealt with the traditional data processing applications Memory Layout of C Programs When the program starts its code gets copied to the main memory The stack holds the memory occupied by functions It stores the activation records of the functions used in the program And erases them as they get executed The heap contains the data which is requested by the program as dynamic memory using pointers Initialized and uninitialized data segments hold initialized and uninitialized global variables respectively A few algorithm examples BIG O notationBig O notation is used in Computer Science to describe the performance or complexity of an algorithm Big O specifically describes the worst case scenario and can be used to describe the execution time required or the space used e g in memory or on disk by an algorithm O void printFirstElementOfArray int arr printf First element of array d arr This function runs in O time or constant time relative to its input The input array could be item or items but this function would still just require one step O n void printAllElementOfArray int arr int size for int i i lt size i printf d n arr i This function runs in O n time or linear time where n is the number of items in the array If the array has items we have to print times If it has items we have to print times O n void printAllPossibleOrderedPairs int arr int size for int i i lt size i for int j j lt size j printf d d n arr i arr j Here we re nesting two loops If our array has n items our outer loop runs n times and our inner loop runs n times for each iteration of the outer loop giving us n total prints Thus this function runs in O n time or quadratic time If the array has items we have to print times If it has items we have to print times Data StructureLinked Lists A linked list is a linear data structure that includes a series of connected nodes Here each node stores the data and the address of the next node For example You have to start somewhere so we give the address of the first node a special name called HEAD Also the last node in the linked list can be identified because its next portion points to NULL Linked lists can be of multiple types singly doubly and circular linked list In this article we will focus on the singly linked list Representation of Linked ListLet s see how each node of the linked list is represented Each node consists A data itemAn address of another nodeWe wrap both the data item and the next node reference in a struct as struct node int data struct node next Each struct node has a data item and a pointer to another struct node Let us create a simple Linked List with three items to understand how this works Initialize nodes struct node head struct node one NULL struct node two NULL struct node three NULL Allocate memory one malloc sizeof struct node two malloc sizeof struct node three malloc sizeof struct node Assign data values one gt data two gt data three gt data Connect nodes one gt next two two gt next three three gt next NULL Save address of first node in head head one The power of a linked list comes from the ability to break the chain and rejoin it E g if you wanted to put an element between and the steps would be Create a new struct node and allocate memory to it Add its data value as Point its next pointer to the struct node containing as the data value Change the next pointer of to the node we just created Doing something similar in an array would have required shifting the positions of all the subsequent elements Binary Search Tree Binary search tree is a data structure that quickly allows us to maintain a sorted list of numbers It is called a binary tree because each tree node has a maximum of two children It is called a search tree because it can be used to search for the presence of a number in O log n time The properties that separate a binary search tree from a regular binary tree isAll nodes of left subtree are less than the root nodeAll nodes of right subtree are more than the root nodeBoth subtrees of each node are also BSTs i e they have the above two properties The binary tree on the right isn t a binary search tree because the right subtree of the node contains a value smaller than it Searching a key For searching a value if we had a sorted array we could have performed a binary search Let s say we want to search a number in the array in binary search we first define the complete list as our search space the number can exist only within the search space Now we compare the number to be searched or the element to be searched with the middle element median of the search space and if the record being searched is less than the middle element we go searching in the left half else we go searching in the right half in case of equality we have found the element In binary search we start with n elements in search space and if the mid element is not the element that we are looking for we reduce the search space to n we keep reducing the search space until we either find the record that we are looking for or we get to only one element in search space and be done with this whole reduction C function to search a given key in a given BSTstruct node search struct node root int key Base Cases root is null or key is present at root if root NULL root gt key key return root Key is greater than root s key if root gt key lt key return search root gt right key Key is smaller than root s key return search root gt left key Illustration to search in below tree Start from the root Compare the searching element with root if less than root then recursively call left subtree else recursively call right subtree If the element to search is found anywhere return true else return false Insertion of a key A new key is always inserted at the leaf We start searching a key from the root until we hit a leaf node Once a leaf node is found the new node is added as a child of the leaf node C program to demonstrate insertion in a BST recursively include lt iostream gt using namespace std class BST int data BST left right public Default constructor BST Parameterized constructor BST int Insert function BST Insert BST int Inorder traversal void Inorder BST Default Constructor definition BST BST data left NULL right NULL Parameterized Constructor definition BST BST int value data value left right NULL Insert function definition BST BST Insert BST root int value if root Insert the first node if root is NULL return new BST value Insert data if value gt root gt data Insert right node data if the value to be inserted is greater than root node data Process right nodes root gt right Insert root gt right value else Insert left node data if the value to be inserted is greater than root node data Process left nodes root gt left Insert root gt left value Return root node after insertion return root Inorder traversal function This gives data in sorted order void BST Inorder BST root if root return Inorder root gt left cout lt lt root gt data lt lt endl Inorder root gt right Driver codeint main BST b root NULL root b Insert root b Insert root b Insert root b Insert root b Insert root b Insert root b Insert root b Inorder root return Output Arrays An array in C C or be it in any programming language is a collection of similar data items stored at contiguous memory locations and elements can be accessed randomly using indices of an array They can be used to store collection of primitive data types such as int float double char etc of any particular type To add to it an array in C C can store derived data types such as the structures pointers etc Given below is the picture representation of an array There are various ways in which we can declare an array It can be done by specifying its type and size by initializing it or both Array declaration by specifying size C code below Array declaration by specifying sizeint arr With recent C C versions we can also declare an array of user specified sizeint n int arr n Array declaration by initializing elementsint arr Compiler creates an array of size above is same as int arr Array declaration by specifying size and initializing elements Array declaration by specifying size and initializing elementsint arr Compiler creates an array of size initializes first elements as specified by user and rest two elements as above is same as int arr Advantages of an Array in C C Random access of elements using array index Use of fewer line of code as it creates a single array of multiple elements Easy access to all the elements Traversal through the array becomes easy using a single loop Sorting becomes easy as it can be accomplished by writing fewer line of code Thanks for reading Hope you learnt something new todayCheers	2022-03-09 05:47:43
