Hello all,

My question is very simple.
What does it take for a newbie to solve a Medium problems in general.
Let me give some context. I started working on Leetcode easy problems while improving my skills in basic data structures and basic algorithms.
After 3 weeks working with the same pace, I feel I am getting used to easy problems.
It's like Easy problems require to only know some basic theory.
Now what about Medium problems ? Any examples ?

Thanks a lot in advance for your answers.
