I've posted a few blogs since early December 2023. I'll define the difficulty level of the blogs with the below scale.
The difficulty level of my blogs are as follows:
Easy — solved within 2 hours
Medium — solved within 2~4 hours
Hard — couldn't be solved alone and peeked at the solution/ got help from a friend
Ex — completely out my skill range, took me a 1/2 days to understand the solution
Note that these are my personal opinions on the problems' difficulty.
It differs from person to person since some people are just better at certain topics.
Upd: why am I getting downvoted?
