I've been prepping for coding interviews and I keep getting mixed signals about which patterns to focus on. Some say trees and graphs are essential, while others emphasize dynamic programming. Feels like there's too much info out there.

I’ve been trying to prioritize common problems like recursion and searching algorithms. Was surprised by how often I hit the same types of problems across different platforms. It’s frustrating to feel like I’m missing something big. Anyone have thoughts on the most commonly tested patterns or whether I should dive deeper into a specific area?
