Okay this is for gurus, developers and any one who got the idea. What approaches did you use or are you using to tackle data structure and algorithm, cause these two is like the stronghold of computer science, know the how to's in algorithm and data structure then you can write in any language so far its capable. (I stand to be corrected though). So my questions are What are the approaches you used in tackling (learning) these two. What materials did you use (vids, books, mp3 etc). And sure any online resources??
