Ask HN: What are good resources to learn dynamic programming?

I understand the basic ideas behind dynamic programming (and I think it's really cool and very useful tool to understand), but I struggle with DP programming on Leetcode and in interviews.

Are there any good resources out there for DP? Multiple sources have said that DP feels like "magic" when you don't get it, but once it "clicks" DP problems become very easy. I'm still waiting for it to click.
