Hello, cp noob here.

After doing some USACO and Google Kickstart problems, it seems like CodeForces problem sets involve much more mathematical insights. I feel like I often get caught up in these mathematical inquiries and can implement the data structures/algorithms part more easily. Am I right?

I find USACO silver problems to be much more enjoyable/manageable when compared to CodeForces Div 2 A-D. Perhaps it's just that CodeForces is harder in general?

If I just want to learn computer science in its "purest form" (algorithms/data structures), should I continue to do CodeForces? Thanks in advanced.
