- ### Dynamic Programming
- **NOTE:** DP is a valuable technique, but it is not mentioned on any of the prep material Google provides. But you could get a problem where DP provides an optimal solution. So I'm including it. - ### Dynamic Programming - This subject can be pretty difficult, as each DP soluble problem must be defined as a recursion relation, and coming up with it can be tricky.
