I heard about neetcode 150 and i directly started solving it topic wise ... And i completed the array topic questions But i noticed most of them were medium questions , i know i won't be able to solve most and i had to look at the solutions for almost every single one of them. Now when j have finished the array questions i don't think i fully understand and solve array questions yet .. i am confused should i go further or try a different list that contains more questions probably start from easy cause i want to build my confidence and clear my fundamentals ... I am really confused please guide me Thank you so much ! Btw i have completed algorithms 1 by princeton so i do understands data structures i just need to practice them
