BE: Leetcode API integration #77
Description
I currently don't have a vision for what leetcode stats to do. Start with the following but also check in with me abt it:
- get # of problems solved broken down by difficult (easy / medium / hard)
- filter these problems by a category. Due to possible inconsistencies between codeforces categories and leetcode categories, you'll need to either manually write a dictionary that correlates one between the other, or use a vector-search tool to find which category is more similar (I'm obviously suggesting the former but the latter would be lowkey cool too)
