What are some common mistakes in greedy algorithms?

What are some common mistakes in greedy algorithms?

Common mistakes include assuming local optima lead to global optima, and not considering all possible solutions.

Can you give an example of a greedy algorithm mistake?

Sure! A classic example is the coin change problem, where choosing the largest coin first doesn't always yield the best solution.

How can I avoid these mistakes?

To avoid mistakes, always analyze the problem to ensure a greedy approach is suitable and consider edge cases.

Are there specific problems where greedy algorithms work well?

Yes, greedy algorithms work well in problems like Huffman coding, Kruskal's algorithm for MST, and activity selection.
