  • Welcome aboard
    Welcome to the course
  • Interview based Puzzle Questions
    This helps you to understand how to convert logic and write it in the form of diagrammatic and textual way.
  • Operating Systems
    This is asked quite often in interviews in this we will cover all the major things asked in interviews starting from types of OS, Process management, Memory and disk management etc. Also, the classical problems asked in Interviews are covered in great depth.
  • Computer Networks
    In this section we will understand multiple types of network layers(data & network etc.) and later covering all the other important topics along with the Interview problems.
  • Database management system
    DBMS is itself an important thing be it in terms of moving towards development or cracking placement interviews. We will understand SQL queries, Normalizations, Schedules, Transaction and Concurrency etc. in great depth to help you master this topic.
  • Web Technologies
    Internet Protocols are an important part of web here we will understand the architecture and working of the search engines along with the web frameworks.
  • Arrays
    This is the one of most important data structure that is generally easy to understand but algorithms and concepts of this topic can be very tricky and it is asked in almost every tech company.
    Algorithms such as Binary Search, Sorting, Maximum Subarrays, and Searching are must to do in order to get a good grasp of this topic.
  • Character Arrays
    This is another type of an array, just that you need to understand how to handle strings using character arrays, It will help you understand how the variation of data type in array change the way we handle this data structure.
  • Pointers
    This most important topic to understand in order to move towards the advanced data structures, it is just like another datatype to help store address of memory we create to store data.
  • Algorithms STL
    STL is one of the most useful thing that to write codes in a faster way, this is something comes very handy in competitive programming and online coding practise sites.
  • Bitmasking
    In this section, we will understand how Bitwise operators like AND, OR, XOR, and NOT to work on machine code to help write the programs that works faster, since computer understands machine code. This concept is also very useful in Recursion as well as Dynamic programming advanced concepts.
  • Strings
    It's an alternative to Character Array, Strings data type helps in handling string easier and faster. In depth understanding of this concept becomes easier after understanding OOPs concepts.
  • Recursion Introduction
    Inorder to understand Recursion we must understand Recursion, so this is what is focussed here i.e. write codes using Recursion.
    It is used in Dynamic Programming and as well as in data structure such as Trees, Graphs, and Heap etc.
  • Deep Diving into recursion
    In this section, we will start exploring how to form recurrence relations using problem statements and mainly discussing recursion on arrays and strings.
  • Recursion on Subsets
    In this section, we will understand how to solve algorithms such as phone search and advanced concept of Knapsack that is mostly asked in Interviews.
  • Backtracking
    It is the most important concept to understand in Recursion and it is thoroughly checked in Interviews and Technical Rounds. If one has to master recursion they need to master backtracking.
  • Time and Space Complexity
    It helps us to compare the algorithms on the basis of Time and Space it takes to run the code and help us to master how to write codes by considering constraints of the problem.
  • Object Oriented Programming
    One of the most important topic to build data structures, this is not only used in every data structure but also help us to understand how to associate the real world with programming language.
  • Vectors
    This data structure is used to store data and avoid the hustle of dynamic memory allocation to increase the space manually. Used in topics such as Dynamic Programming, Hashmaps, Graphs etc.
  • Linked List
    In this topic we learn how to store data in a non-contiguous manner and we understand how the Linked List can work in a better time complexity that other data structures in some operations.
  • Stack
    It follows the principle of Last In and First Out, although this data structure can be easily understood but the concept of LIFO can be used to solve some typical problems such as Histogram Area, Stock Span, and Balanced Parantheses etc.
  • Queues
    This data structure works just like a normal queue does and it is mainly used as a helping data structure in Trees and Graphs.
  • Deque
    It will help you in the Interview questions based on Sliding Window.
  • Binary Trees and Binary Search Trees
    In this data structure, we learn how to store data in a hierarchical format. It is one of the most important topic from Interview point of view and questions from this topic is frequently asked in companies such as Amazon, Microsoft, Flipkart and Google etc.
  • Heap
    This data structures helps you to understand how the infinite stream of data coming can be accessed to fetch the useful information, for example, find the most sold products on any website?
  • Hashmap
    It helps us to understand how we can store, update and delete the data in constant time. It is majorly used in Dynamic Programming and Graphs to help us make the time complexities of the algorithms better.
  • Graphs
    The most popular data structures in companies like Direct-i, Google, and Arcesium etc.
    It is usually considered tough because of the dependency on other data strucutres such as queue, hashmaps, sets, and heap etc. but once you get a taste of how to apply these things together it will make you a better programmer.
  • Tries
    It helps us to search in constant time and incase you want to use auto suggestions features of Amazon, Flipkart or other sites search bar this is the solution.
    Many problems such as Maximum-Xor, and Maximum Sum etc. uses tries to help improve complexity of the problem.
  • One Dimensional Dynamic Programming
    We learn how we can improve the time complexities of Recursive algorithms drastically using concepts like Top Down approach. Also we convert out Top down approach to bottom up approach using the recurrence relation and DP concept, it's exactly what is required for the master DP.
  • Two Dimensional Dynamic Programming
    The most important concepts of DP are Knapsack, Optimal Game strategy, and solving string problems using 2D storage there by improving their complexities multiple folds.
  • Top DP Algorithms
    Knapsack, LCS, LIS, Matrix Chain Multiplication are amongst the topics/algorithms that one should know to crack top placements.
  • Greedy Algorithms
    This is where you learn how being greedy can benefit you to solve certain problems in a faster way. The main point of focus here is to understand where we can apply Greedy over Dynamic Programming.
  • Real life projects
    In this section we will cover the real world applications of the algorithms that we did in the course itself. Building applications like Splitwise algorithms and Sudoku Solver etc.
  • Policy Based data structures
    We will give you a breif about how the policy based data strucutres can help you in certain aspects.
  • Number theory
    In this section we will cover how the number theory concepts can be used in solving advanced problem solving and writing optimised code.
  • Advanced String matching Algorithms
    In this section we will cover algorithms such as Rabin Karp, Trie searching and other string matching algorithms.
  • Top Tech Company Questions
    Practise from the most asked questions in companies such as Amazon, Facebook, Microsoft, LinkedIn, and Google etc. Become the programmer to crack any of your dream company.
  • Google, Amazon, GoJek, Flipkart, Uber, Amex Interview mantras
    This will give you an idea of how you should prepare yourself for the final interviews and prepare yourself for everything that you may face during the placement process of any company.
  • Faang Interview Questions
    In this we will understand how to tackle the questions asked in big wigs, we will around 150+ Questions specifically curated for the interviews of FAANG companies.
