Leetcode Problems Are HARD!!
I decided to learn C++ (1.5 years ago i had learn C++ because of my uni class but i have forgot almost all of it). So what i do is when i learn a concept (Linked Lists for example) i find a Leetcode problem BUT it takes hours and hours. Like I have seen that in just a week i have relearn a lot of C++ but again a med difficulty can take up to 4 hours and i dont know if its normal or if i am stupid
