A 12-week, mentor-led DSA course for students and working professionals in Patna — join live online from anywhere in Bihar, or train in person at our Patna center. Learn arrays to graphs in Java & C++, and walk out interview-ready.
The short answer, before the deep dive.
Data Structures & Algorithms (DSA) is the study of how to organize data efficiently (using structures like arrays, linked lists, trees, and graphs) and how to process that data using step-by-step logic (algorithms) that's fast and resource-light. It's the core subject tested in almost every technical coding interview — at product companies, service-based IT firms, and government exams like GATE — because it measures how well you can actually solve problems, not just write syntax.
For students and job seekers in Patna, a strong DSA foundation is often the single biggest factor separating a shortlisted resume from a converted job offer. JavaBomber's DSA course is built specifically to close that gap — through daily problem-solving, not just lecture-style teaching — whether you join our live online batch or train in person at our Patna classroom.
Online or offline, the course adapts to where you're starting from.
Build the DSA foundation companies test in campus placements and off-campus drives, alongside your college coursework.
Preparing for a switch to a product-based role or a better package — join evening or weekend batches around your job.
Learners from Bihar Sharif, Muzaffarpur, Gaya, and beyond join the same live classroom experience through our online batch.
Already know a language but struggle with interview-style problems? This course sharpens problem-solving, not syntax.
Nine modules, taught in order of increasing complexity — each with its own problem sets and complexity analysis.
Foundations of Big-O and Big-Θ analysis, two-pointer and sliding-window techniques, in-place array manipulation, and common string-processing patterns.
Singly, doubly, and circular linked lists — reversal, cycle detection, merging, and the classic linked-list interview problems.
Stack- and queue-based problem patterns, monotonic stacks, circular queues, and their use in expression evaluation and BFS traversal.
Recursive thinking, recursion trees, and backtracking for permutations, combinations, and constraint-satisfaction problems like N-Queens and Sudoku solvers.
Merge sort, quicksort, heap sort, and binary search variants — with a focus on when each algorithm is the right tool.
Tree traversals (in-order, pre-order, post-order, level-order), BST operations, balanced trees, and tree-based interview questions.
Min-heaps and max-heaps, priority queue applications like the top-K problem, and tries for prefix-based search and autocomplete.
Graph representations, BFS & DFS, topological sort, shortest-path algorithms (Dijkstra, Bellman-Ford), and union-find for connectivity problems.
Memoization vs. tabulation, classic DP patterns (knapsack, LCS, LIS), and greedy algorithms — closing with two weeks of mixed mock interviews.
The same environment used in real technical interviews.
Same syllabus, same mentors, same certificate — pick whichever fits your routine.

RAVI RAJ THAKUR
Lead DSA Trainer, JavaBomber
RAVI RAJ THAKUR has spent over six years writing production Java and mentoring students through technical interview preparation, after beginning his own career solving competitive programming problems. At JavaBomber, he leads the DSA batches with an emphasis on pattern recognition over memorization — teaching students to recognize which of the nine curriculum modules a new problem belongs to, rather than relying on rote solutions.
"I joined the online batch from Bihar Sharif and never felt like I was missing out on the classroom experience. The weekly contests kept me consistent."
"Coming from a non-CS background, recursion and DP felt impossible at first. The module order made everything click in sequence."
"The mock interviews in the last two weeks were the closest thing to my actual interview. That prep made the real thing feel familiar."
Our Patna classroom is easily reachable from across the city, and our online batch reaches every corner of Bihar.
Students regularly join our classroom batch from across Patna, including:
And through our live online batch, students join from well beyond the city, including:
DSA stands for Data Structures & Algorithms — the methods used to organize data (arrays, trees, graphs) and the step-by-step logic used to process it efficiently. It's important because almost every technical coding interview at product-based and service-based companies tests DSA problem-solving skills, and strong DSA foundations make you a faster, more efficient programmer in real projects.
Yes. JavaBomber's DSA course runs as live, instructor-led online classes, so students anywhere in Patna, Bihar, or elsewhere can join without commuting. The same course is also available in-classroom at our Patna training center for students who prefer face-to-face learning.
The course is taught primarily in Java, with C++ implementations covered for core data structures as well, so students comfortable in either language can follow along and apply the concepts in technical interviews.
The course runs for 12 weeks with live classes three times a week, plus weekly problem-solving contests. The fee is ₹13,999, with installment options available for both the online and Patna classroom batches.
Basic familiarity with any programming language and simple loops or functions is enough to start. Students who've completed JavaBomber's Core Java course, or an equivalent beginner course, will find the transition especially smooth.
The syllabus covers arrays and strings, linked lists, stacks and queues, recursion and backtracking, sorting and searching algorithms, trees and binary search trees, heaps and priority queues, tries, graphs (BFS/DFS, shortest paths), and dynamic programming, alongside time and space complexity analysis throughout.
Yes, the course is structured around interview preparation, with weekly timed contests, curated problem sets from real interview questions, and mock technical interviews in the final two weeks, in addition to core concept teaching.
Yes. Alongside weekday evening batches, JavaBomber runs dedicated weekend batches for working professionals and college students with weekday commitments, in both the online and Patna classroom formats.
The Core Java course teaches Java language fundamentals and object-oriented programming. The DSA course assumes basic programming knowledge and focuses entirely on data structures, algorithms, and problem-solving for technical interviews — the two are complementary rather than overlapping.
Yes, every live online class is recorded and shared with enrolled students, so missing a session doesn't mean missing the content.
Join the DSA course online or at our Patna classroom — batches forming now for weekday and weekend cohorts.
