How do computer scientists decide that programming is not intellectually rewarding enough for them? Maybe they have not considered programming their own apps instead of implementing what someone else wants?

Still struggling with coding interviews(leetcode)

Posted: 28 Feb 2021 09:55 PM PST

I'm a junior in college now, for past year I have been trying to learn and understand DS/Algos, but I still cannot do any medium leetcode questions, I have maybe 20 easy questions in past 6 months in Leetcode.

I know leetcode skills don't really apply to real world but I need those skills to land a decent job/internship.

What's the secret to mastering leetcode?? My primary language is python, are there any courses specifically made for coding interviews?

I have been told to get CTCI book, but is there a python version/for that book?

Question about materials

Posted: 01 Mar 2021 01:20 AM PST

Hello!

Is there exist any magazines/journals about modern compiler design? I found only several books, but I want to read modern papers in this area. Specifically I'm interested in optimizations and data flow analysis.

There are a couple of solutions that I saw on the internet, but I'm interested in arriving at a general solution for a number N<=10.

Just to be clear, I'm preparing for an interview and this seems to be a potential question.

Am I understanding rehashing correctly?

Posted: 28 Feb 2021 07:56 AM PST

IIRC rehashing is when you have a hash table (created with whatever method: separate chaining, linear probing, quadratic probing, double hashing), and then you create a new table (generally double the old size, then find the next prime number greater than this), and linearly scan the old table, applying the new hash function to each value, placing it in the new table

Is this a correct understanding?

On a data structures assignment I apparently bombed questions having to do with hash tables, which totally blows because it wasn't for lack of trying. As I was doing them I had no "oh wait I don't understand this" thoughts, I totally thought I understood everything.

I found this great treasure from the machine learning sub It would be wonderful if you have any similar inputs for us
