I have this doubt from a very long time about tags of the problems.when problem have tags like dp, greedy and brute force (1600+ rated problems), so is it really mean that the problem can be solved independently with these tags.Does that mean, I can solve the problem using just greedy approach without some precomputation of dp or any brute force.How these tags decided ?








Any user with a CM rating or higher can add tags.

The tags only serves as a suggestion to what you might need to solve this problem, but it does not necessarily mean you have to know/use all of them, a problem has many solutions, maybe one uses greedy, but another uses dp
