Greedy Algorithms

When making the locally best choice produces the globally best answer.

Why learn Greedy Algorithms?

  • Often the simplest correct solution exists — if greedy works.

  • Teaches you to reach for proofs (exchange argument) before code.

  • Frequent in scheduling, intervals, and resource problems.
