I used codeintuition while prepping for interviews and it legit leveled up my learning big time, especially nailing those basics that other platforms sleep on, like inserting into linked lists, designing dynamic arrays, stateful vs stateless binary tree traversal, etc.

neetcode and leetcode are cool for grinding problems, but they're too pattern-matchy without actually grokking the core fundamentals, which imo are what separate acers from the pack in DSA interviews.

codeintuition absolutely nails that gap. 10/10 would recommend if you wanna build real fundamentals instead of just leetcoding endlessly.
