Data Structures and Algorithms
The DSA course covers the patterns that show up in placement rounds and online assessments, and reinforces them with:- Mock assessments that mirror the timing and difficulty of real company rounds.
- Past contest problems curated so you can practice on questions that have actually appeared in competitive programming contests.
- Direct handoff into the DSA Sheet so every concept has a paired 400-problem pattern-based drill.
Five-Phase Competitive Programming Track
The CP track takes you from your first C++ program to the advanced structures and graph techniques that decide top ranks in contests.1
Phase 1: C++ Programming Foundations
Set up your toolchain and get fluent with C++ syntax, standard library containers, and the idioms that make CP code fast to write.
2
Phase 2: Core Problem-Solving Patterns
Build the reflexes for the recurring techniques that carry across contest problems and interview rounds.
3
Phase 3: Intermediate Data Structures
Level up into the data structures that separate contest solvers from casual coders, with focused practice on each.
4
Phase 4: Advanced Data Structures
Take on the advanced structures used in higher-rated problems, with worked examples and drills.
5
Phase 5: Graph Theory
Finish with graph theory, from traversal to the deeper algorithms that unlock hard contest problems.
