What is a K-connected Graph
a K-connected Graph (what is) is simple if you keep it on paper. Priya uses it for bus routes in a city map.
a K-connected Graph (what is) on the board: BFS queue / DFS stack. Then say what bus routes looks like after.
a K-connected Graph (what is) exists so Priya can keep bus routes correct in a city map.
a K-connected Graph (what is) shows up in a city map. Name bus routes, not “a real-world scenario”.
a K-connected Graph (what is) trap — no visited set → infinite loop. Priya loses marks for that every viva.
After a K-connected Graph (what is), Priya should still remember no visited set → infinite loop.
Viva for a K-connected Graph (what is): what it is → BFS queue / DFS stack → the mistake (no visited set → infinite loop).
For a K-connected Graph (what is): definition + a city map + one failure.
