Hello everyone! I am a newbie and have been pretty new to CP. I have practiced some problem solving strategies and some really basic concepts like "greedy" and "brute force". How do I learn more algorithms and practice them for USACO Silver/Gold? Thanks!
Some good resources:
https://usaco.guide/
http://darrenyao.com/usacobook/java.pdf OR http://darrenyao.com/usacobook/cpp.pdf

I would recommend going through Usaco Guide (first link), they have basically everything you need for USACO
