Data Structures & Algorithms Course in Mohali — 2026–27 Updated Syllabus

The data structures and algorithms course in Mohali at techcadd follows an updated 2026–27 syllabus covering arrays, strings, linked lists, stacks, queues, trees, graphs, hashing, searching, sorting, recursion and algorithm analysis. It is designed to strengthen problem-solving for university exams, coding rounds and technical interviews.

Why Learn Data Structures and Algorithms

Data structures decide how information is stored; algorithms decide how it is processed. Together they determine whether a program is fast and memory-efficient or slow and wasteful.

Technical interviews at product and service companies often test DSA directly through coding problems, which is why many students and job seekers make it a priority.

Updated 2026–27 Syllabus

Programming Foundations and Complexity

Choice of language (C++, Java or Python), time and space complexity, Big-O, Big-Theta and Big-Omega notation, and analysing loops and recursive functions.

Arrays and Strings

Prefix sums, two-pointer and sliding window techniques, string matching, and common interview patterns.

Recursion and Backtracking

Base cases, recursion trees, permutations, subsets, N-Queens and Sudoku-style problems.

Linked Lists, Stacks and Queues

Singly, doubly and circular lists, reversal and cycle detection, stack applications like expression evaluation, queues, deques and monotonic stacks.

Searching and Sorting

Linear and binary search, binary search on answer, bubble, insertion, selection, merge, quick, heap and counting sort, and when to use each.

Hashing

Hash maps and sets, collision handling, frequency counting and hashing-based problem patterns.

Trees and Binary Search Trees

Traversals, height and diameter, lowest common ancestor, BST operations and an introduction to balanced trees.

Heaps and Priority Queues

Min and max heaps, heapify, top-k problems and merging sorted lists.

Graphs

Representations, BFS, DFS, topological sort, Dijkstra's algorithm, minimum spanning trees with Prim's and Kruskal's, and union-find.

Greedy Algorithms and Dynamic Programming

Activity selection, interval problems, memoisation versus tabulation, knapsack, longest common subsequence and DP on grids.

How the Course Is Taught

Each topic is explained with diagrams and dry runs, then implemented in code and practised through graded problems from easy to hard. Learners are encouraged to explain their approach aloud, which mirrors how interviews are conducted.

Practice and Assessments

• Topic-wise problem sets after every module

• Timed coding tests to build speed and accuracy

• Practice on platforms such as LeetCode, HackerRank and GeeksforGeeks

• Mock coding interviews with feedback

• A mini project that applies data structures, such as a route finder or autocomplete feature

Who Can Join

B.Tech, BCA, MCA and diploma students, graduates preparing for placements, and working developers who want to sharpen problem-solving can join. Knowing the basics of one programming language is helpful; ask the team if you need a language foundation first.

Duration, Fees and Batches

Contact the techcadd Mohali team for the current course duration, fees, batch timings and language options. These details can change between intakes.

Skills and Career Benefits

A strong DSA foundation supports roles such as software developer, backend developer, SDE trainee and competitive programmer, and helps in subjects like operating systems and databases. Interview success depends on consistent practice, communication and market conditions.

Why Learn DSA at techcadd Mohali

• Structured syllabus: topics ordered so each builds on the last.

• Pattern-based practice: learning recognisable problem patterns rather than memorising solutions.

• Doubt support: help with tricky problems and debugging.

• Interview focus: mock interviews and guidance on explaining solutions.
