Graph Traversal

The video introduces graph traversal, highlighting its differences from tree traversal. It explains the structure and properties of graphs, emphasizing the absence of a root node and the concept of adjacency. The video also covers different types of graphs, the importance of edge values, and the need to track visited nodes during traversal. It concludes with a preview of implementing graphs in code.

How does the concept of adjacent nodes differ in graphs compared to trees?

What challenges might arise when implementing graph traversal algorithms?

Explain the significance of tracking visited nodes during graph traversal.
