12 June 2019 4 INTRODUCTION - session 1

12 June 2019 5 Tell Me about yourself The future depends on what we do in the present - Mahatma Gandhi Born and brought up in Patna, Bihar, I studied in a convent school and it was around my ninth grade where I developed a keen interest in Internet and Technology. Following my interest, I pursued my Bachelors in Computer Application from men’s College, Patna. As part of my curriculum, I particularly found the subjects of Computer Networks and Design of Algorithms highly intriguing, as these subjects created in me a passion to study the computer related courses in much more detail. Alongside, I also started preparing for my Master of Computer Application course. Besides my curriculum, I participated in various events pertaining to art and culture held in my college. Talking about my profession, now I am qualified computer programmer where I work on various programming languages such as C, Java, PHP, JavaScript, C++, Python, Shell, Ruby, Objective-C and C#. Besides my work and academic, I am extremely passionate about playing Guitar, which is a great stress- buster for me. I am very much greatful to my esteem college, faculty and supported my current company which developed myself to effective quality professional. That's all about myself, my quote is "Life is all about grabbing the opportunity". thank you so much for giving me the opportunity to introduce me.

12 June 2019 6 Introduction • What is Project? •A project is a temporary effort to create a unique product or service. Projects usually include constraints and risks regarding cost, schedule or performance outcome.. The future depends on what we do in the present - Mahatma Gandhi

12 June 2019 7 Project Overview • Domain choice of the project ? The difference between a successful person and others is not a lack of strength, not a lack of knowledge, but rather a lack of will.-Vince Lambardi

12 June 2019 8 Introduction • Domain v/s Platform ? Domain Platform It is a field study that defines a set of common requirement Terminology and functionality for any software program constructed to solve a problem in the area of computer programming. EX: PLM, CRM, RETAIL A platform is a “Blue print for the evolution of popular software or specification.” It depends a standard around which a system can be developed. EX: Java platform .Net platform People rarely succeed unless they have fun in what they are doing.-Dale Carnegie

12 June 2019 9 Introduction • Project v/s Product ? Do what you can, with what you have, where you are. -Theodore Roosevelt

12 June 2019 10 Introduction • Project Learning’s ? Anyone who has never made a mistake has never tried anything new. -Albert Einstein

12 June 2019 11 Service & Product Company • People rarely succeed unless they have fun in what they are doing.-Dale Carnegie “Service Based Companies are driven by customer needs. They offer services and solutions as per customer requirements. Features of these type of companies:- 1. High pressure work environment. 2. Completing deadline is most. 3. Person should be multitasking. 4. Should be willing to become a victim of office politics for better appraisal from senior. 5. Less scope of R&D. But would be able to learn new things a lot. Product Based Companies are driven by an idea to help different customers. Here the main focus would be what should i do to make my product better. Features of these type of companies are:- 1. Cool and healthy environment. 2. Better flow of thoughts. Help an individual to think out of the box. 3. Person need not be multitasker. Instead be good at its respective field. 4. Pressure is there but comparative less. 5. More job satisfaction as mind will be less stressful.

12 June 2019 17 Version Management •These are the problems source code management is intended to solve. Effectively it is a database for source code that eases the problems of – Multiple people in many places working on the same code – Retrieving old versions of files – Keeping logs about what changed in a file – Integrating changed code – Generating release builds Version Management also called Version Control or Revision Control, is a means to effectively track and control changes to a collection of related entities. The term "Versioning" is also sometimes used but the difference is that "Versioning" typically refers to when someone manually applies a version number or label to something for easier communication or simplification such as "draft", "beta", or "1.0". In the context of an information solution version control is most often used to track and control changes to source code. It is a very important tool within an overall life cycle management strategy for information solutions.

12 June 2019 18 Version Management •Centralized Version Control A single server holds the code base Clients access the server by means of check- in/check-outs Examples include CVS, Subversion, Visual Source Safe. Advantages: Easier to maintain a single server. Disadvantages: Single point of failure. Distributed Version Control Each client (essentially) holds a complete copy of the code base. Code is shared between clients by push/pulls Example Git Advantages: Many operations cheaper. No single point of failure Disadvantages: A bit more complicated!

12 June 2019 19 Version Management: GIT •o GIT is a Distributed Version Control System. oIt is a content addressable file system, used to track directory trees. oIt handles all the things like merging of source code and maintaining versions. oGIT is optimized for Complex Merges and Fast. oIt follows Trunk Base Development. oIt allows for code collaboration with anyone online. oUsers keep entire code and history on their location machines oUsers can make any changes without internet access Linus uses BitKeeper to manage Linux code o In 2005, BitKeeper suddenly became unavailable. o Linus decided to create a tool with Distributed Source Management System. o Linus Torvalds developed GIT in June 2005.

12 June 2019 20 Terminology • o DIRECTORY : A folder is used for storing multiple files. o REPOSITORY : A collection of all the files and their history organized in folders, branches, tags. o CLONE : Act of copying a repository from a remote server. o BRANCH : It is a pointer to a commit(save the files). o MERGE : Combination of one or more branches into the current branch. o ORIGIN : The default name of the remote repository o MASTER : It is just another branch, but is the default one which gets created. o STAGE FILES : These are the files we have told GIT that are ready to committed. o SNAPSHOT : In general is just the "entity" that GIT uses to store its data. o INTEGRATORS : It can review and bring changes to reference code asynchronously to central repository.

12 June 2019 27 Top 50 IMPORTANT PROGRAMS • o 1. Fibonacci series oWrite a simple Java program which will print Fibonacci series e.g. 1 1 2 3 5 8 13 ... . up to a given number. Be prepare for cross questions like using iteration over recursion and how to optimize the solution using caching and memorization. o2. Prime number oWrite a Java program to check if a given number is prime or not. Remember, a prime number is a number which is not divisible by any other number e.g. 3, 5, 7, 11, 13, 17 etc. Be prepared for cross e.g. checking till the square root of a number etc. o3. String Palindrome oYou need to write a simple Java program to check if a given String is palindrome or not. A Palindrome is a String which is equal to the reverse of itself e.g. "Bob" is a palindrome because of the reverse of "Bob" is also "Bob". Though be prepared with both recursive and iterative solution of this problem. The interviewer may ask you to solve without using any library method e.g. indexOf() or subString() so be prepared for that. o 4. Integer Palindrome oThis is generally asked as follow-up or alternative of the previous program. This time you need to check if given Integer is palindrome or not. An integer is called palindrome if its equal to its reverse e.g. 1001 is a palindrome but 1234 is not because the reverse of 1234 is 4321 which is not equal to 1234. You can use divide by 10 to reduce the number and modulus 10 to get the last digit. This trick is used to solve this problem.

12 June 2019 28 Top 50 IMPORTANT PROGRAMS • o 6. Avoiding deadlock in Java oThis is one of the interesting programs from Java Interviews, mostly asked to 2 to 3 years of experienced programmers or higher. Interviewer simply asked you to write code where a resource is accessed by multiple threads. You need to write code in such a way that no deadlock should occur. The trick to solving this problem is acquiring resources in an order and release them in reverse order e.g. first acquire resource R1 and only if you have got R1 go for R2. This way you can avoid deadlock. o7. Factorial oThis is one of the simplest programs you can expect on interviews. It is generally asked to see if you can code or not. Sometimes interviewer may also ask about changing a recursive solution to iterative one or vice-versa. o8. Reverse a String oThis problem is similar to the String Palindrome problem we have discussed above. If you can solve that problem you can solve this as well. You can use indexOf() or substring() to reverse a String or alternatively, convert the problem to reverse an array by operating on character array instead of String. o 9. Remove duplicates from array oWrite a program to remove duplicates from an array in Java without using the Java Collection API. The array can be an array of String, Integer or Character, your solution should be independent of the type of array.

12 June 2019 29 Top 50 IMPORTANT PROGRAMS • o 0. Printing patterns o11. Print repeated characters of String? o12. GCD of two numbers o13. Square root of number oYou need to write a program to calculate the square root of a number without using the Math.sqrt() function of JDK. You need to write your logic and method to calculate the square root. You can though use popular algorithm e.g. Newton's method. o14. Reverse array in place o15. Reverse words of sentence o16. Leap year o17. Binary search o18. String Anagram oWrite a program to check if two given String is Anagram of each other. Your function should return true if two Strings are Anagram, false otherwise. A string is said to be an anagram if it contains same characters and same length but in different order e.g. army and Mary are anagrams. You can ignore cases for this problem but you should clarify that from your interview. o.

12 June 2019 30 Top 50 IMPORTANT PROGRAMS • o 19. Design a Vending Machine oThis one of the popular OOAD (object oriented analysis and design) question from Java Interviews. You will be given 3 hours to design and code a vending machine satisfying some of the business requirements. You also need to write unit tests to prove your code satisfy those requirements. You can see this article for more object oriented analysis questions. o20. Reverse a number o21. The first non-repeated character of String o22. Finding Middle element of linked list in one pass o23. Pre-order traversal o24. Pre-order traversal without recursion o25. In order traversal o26. In order traversal without recursion o27. Post-order traversal o28. Post order traversal without recursion o29. Print all leaves of binary tree

12 June 2019 31 Top 50 IMPORTANT PROGRAMS • 30. Sort array using quicksort You need to write a Java program to sort an array of integers using quick sort algorithm. You cannot use any library method e.g. JDK or a third party library, which means, you need to first implement the quicksort algorithm and then sort the array. 31. Insertion sort Write a program to implement the insertion sort algorithm in Java. The program should take an unsorted array and sort it using insertion sort algorithm Also explain the best case and worst case time and space complexity of Insertion sort algorithm. 32. Bubble sort Write a program to implement the bubble sort algorithm in Java. You can use basic operators and functions but sorting functions from Java API is not allowed. 33. Transpose a matrix 34. Print all permutations of String Write a Java program to print all permutations of a given String. For example, if given String is "GOD" then your program should print all 6 permutations of this string e.g. "GOD", "OGD", "DOG", "GDO", "ODG", and "DGO".

12 June 2019 32 Top 50 IMPORTANT PROGRAMS • o35. Reverse a String in place o36. Adding two matrices in Java o37. Matrix multiplication o38. Removal all white space from String o39. Reverse a linked list oWrite a program to reverse a singly linked list in Java. You can use iteration and recursion to solve this problem but you should reverse linked list in place. o40. Find the length of linked list oJust write a program in Java to find the length of a singly linked list in one pass i.e. in just one iteration of singly linked list. o41. Check if linked list has loop oWrite a program to check if given linked list has a loop or not. Sometimes a linked list get corrupt and two nodes point to the same node, which forms the loop or cycle in the linked list. o42. Find the start of loop in linked list

12 June 2019 33 Top 50 IMPORTANT PROGRAMS • o43. Find middle element of linked list o44. Find the 3rd element from the tail linked list oYou need to write a program to find the 3rd element from the tail of a singly linked list. You need to solve this problem without iterating twice o 45. Sort a linked list oYou need to given an unsorted linked list and you need to write a program in Java to sort them in ascending order of the values in each node. o46. Iterative Quicksort oYou need to write a Java program to implement quicksort sorting algorithm without recursion. You can use essential JDK classes and programming constructs, but recursion is not allowed. o46. Bucket sort oThis program is increasingly getting popular on Java interview because it sorts a given array in linear time. Though there are a lot of prerequisite e.g. you must know the maximum value present in the array, it is a very interesting problem from interview point of view. You need to write a program to implement bucket sort algorithm in Java. If you are not familiar with Bucket sort or any other linear sorting algorithm,

12 June 2019 34 Top 50 IMPORTANT PROGRAMS • o48. Check if two string rotation of each other oWrite a program which accepts two given String and checks if they are the rotation of each. If they then return true otherwise return false. A String is said to be a rotation of other string if they contain same characters and the sequence is rotated across any character e.g "dabc" is a rotation of "abcd" but "dbac" is not. If you want to practice more string based questions, o49. LRU cache in Java oWrite a program to implement an LRU cache in Java. An LRU cache means Least Recently Used Cache which removes the least recently used element if the cache is full. You can use LinkedHashMap to implement LRU cache in Java. o50. Merge sort oImplement the merge sort algorithm in Java. You can write a recursive or iterative solution, whichever you like. You also need to explain the time and space complexity for the best, worst, and average case.
