Graph Coloring (Greedy)
Assign colors to vertices such that no two adjacent vertices share the same color. The greedy approach gives an upper bound on the chromatic number.

What is the chromatic number of a graph?
The short version
Think of scheduling exams. No two exams can happen simultaneously if they share students. Assigning time slots is like coloring: adjacent nodes (shared students) need different colors (times).

When to reach for this
- Assign labels with adjacency constraints
- Scheduling with conflicts
- Partitioning into independent sets
- Keywords: 'no two adjacent', 'bipartite', 'conflict'
