Foundations #09 - Graphs
Track: Foundations
Kaun kis se juda hai uski list, ek lehar jo layer-by-layer failti hai, ek raasta jo end tak jaake wapas aata hai, aur ek line jo har cheez ko uske sahi order mein nikaal deti hai.
Before you start. Pichhle lesson mein dekha tree bhi ek graph hai, bas usme cycle nahi hoti - ghoom ke wapas usi jagah aane wala raasta (Foundations #08 - Trees & Recursion). Queue aur stack jo yahan chalte hain wahi hain jo Foundations #06 - Stacks & Queues mein dekhe the - bas ab cycle ho sakti hai, isliye ek nayi cheez chahiye: yaad rakhna kaun dekha ja chuka hai.
