Question 1

What is a greedy algorithm?

Accepted Answer

A greedy algorithm is an algorithmic paradigm that makes the locally optimal choice at each step with the hope of finding a global optimum. It does not always yield the most optimal solution, but it is often efficient and can provide a good approximation.

Question 2

What is the difference between greedy algorithms and dynamic programming?

Accepted Answer

Greedy algorithms make a choice that seems best at the moment and then solve the subproblems that arise later. Dynamic programming, on the other hand, solves all subproblems and then combines their solutions to find the optimal solution for the main problem. DP guarantees an optimal solution, while a greedy approach may not.
