Forgetting previous problems? — Transcript

Full transcript

1. 0:00I've been doing DS algo for quite a long
2. 0:02time but I don't recall any of the
3. 0:04previous topics that I've done a few
4. 0:06days back. I have a very simple solution
5. 0:08and I've been following this for the
6. 0:10last few years and it does work very
7. 0:13well. First of all understand that DS
8. 0:16algo is not about cramming up 300
9. 0:19problems from a sheet. It's about
10. 0:20understanding patterns and it's about
11. 0:23understanding certain algos. So imagine
12. 0:26if you're doing a topic like binary
13. 0:28search and it has four kind of patterns
14. 0:31and you're solving 20 problems on those
15. 0:33four kind of patterns. You shouldn't be
16. 0:35remembering all the 20 problems. Rather
17. 0:38four patterns, two problems for each
18. 0:41pattern. Put them into a notebook and
19. 0:44every week once revise that entire
20. 0:48notebook. It will take 2 to 3 hours. But
21. 0:50what will happen is after 3 months
22. 0:53you'll literally have every pattern on
23. 0:55your fingertips and also try to note
24. 0:58down the algos over here because there
25. 1:00are certain algos that you will be
26. 1:02forgetting. So it's very important that
27. 1:03you put them into the notebook as well.
28. 1:06Do not cram rather revisit the patterns,
29. 1:10understand it and eventually when you
30. 1:13get into an interview and you get a
31. 1:15question, you will be able to map it
32. 1:17into a pattern because you will have all
33. 1:19the patterns and algos over here. Got
34. 1:22it? And you can follow me for such more
35. 1:24placement advices. Thank you so much.
