9๏ธโƒฃ Graphs (Intro / Placement Level)

  • Graph basics: vertices, edges, adjacency list/matrix

  • BFS (Breadth-First Search)

  • DFS (Depth-First Search)

  • Shortest path intro (BFS for unweighted)

  • Typical problems:

    • Find connected components

    • Detect cycle (undirected / directed โ€“ concept)

    • Path existence between two nodes

 

๐Ÿ”Ÿ Practice & Interview Prep

  • Problem-solving strategy:

    • Understand โ†’ Plan โ†’ Code โ†’ Test โ†’ Optimize

๐Ÿ›  Implementation Language

You can mention this clearly on your page:

Primary implementation: C++ / Java / Python (choose one or two)
Explanations are language-agnostic, focus on logic.

โ“ FAQs

Q1. I know syntax but get stuck in problems. Will this help?
โœ… Yes, this course is specifically for people who know a language but struggle with approach and logic.

Q2. Which language will you use in class?
๐Ÿ‘‰ You can write:
โ€œWe primarily use C++/Java/Python in coding examples. Logic remains same in all languages.โ€

Q3. Is DSA necessary if I only want to do web development?
โœ… If you want good jobs in serious companies, DSA helps a lot in interviews and problem-solving, even for web developers.

Q4. Is this for 1st year or final year?
โœ… Ideal from 2nd year onwards, but serious 1st-years are also welcome. Earlier you start, easier placements become.

Q5. Will we get practice questions?
โœ… Yes. Each topic comes with assignments, coding questions and MCQs for revision.
