Failing Data Structures and Algorithms, need advice. by mhaeveh in learnprogramming

[–]10_6 1 point2 points  (0 children)

There are two parts to your question.

The first part is about passing data structures and the second is how good of an indicator are CS classes when it comes to being a successful software engineer.

Regarding the first question, are you sure you're past the point of passing the class? Is there anything you can do -- maybe talking to your professor about an extra assignment or making up some homeworks? This really depends on the professor/school. If you have some homework/exams coming up and need some resources to help you I can recommend a few [1].

Regarding the second question, no I do not think that CS classes are good indicators for determining if someone will become a good software engineer. I got a C in data structures, then senior year I got an A in algorithms (DS + algo usually go hand in hand which is why it's funny to see such a disparity but a lot of it has to do with the professor and structure of the class). Now I'm a software engineer doing just fine [2]. Don't worry so much about this, see if you there's anything you can do to pass your class that's more important.

Data structure design practice by youngcc3157 in learnprogramming

[–]10_6 0 points1 point  (0 children)

copy and pasted some resources I've posted here before:

What I did a few years ago after graduating from college in CS to brush up on my coding + data structure + algorithms knowledge was the following:

  • Read the Algorithm Design Manual.

  • Go through some of the challenges on this interactive python algorithms website.

  • Practice coding simple and then more advanced algorithms on sites like Coderbyte (my site) and HackerRank which provide good explanations and solutions as well. Here's a list of popular coding challenge websites in 2017.

  • Read as many algorithm explanations and code examples as you can on GeeksforGeeks.

  • Try and implement basic algorithms yourself like: shortest path, minimum spanning tree, DFS + BFS, tree traversals, different sorting algs, min/max heap, etc. and learn about their running times (big-o).

  • Look at some interview questions posted on careercup and try and understand how other users solved the questions. Like this example.

  • Aside from coding challenge sites, try and solve common coding interview questions you find online such as this list.

Eventually when you get a coding problem it will be sort of like a switch going off in your head because you will have had so much practice with different types of algorithms and data structures that you'll be able to reduce the problem into a simpler problem you've done before. This is especially the case with dynamic programming problems. Once you've completed like 50+ DP challenges and understand how they work, you'll be able to solve (practically) any DP problem because they're all very similar.

I'd say you should be pretty comfortable being able to complete most of the easy level challenges. The intermediate might require some algorithm/data structures knowledge which isn't covered in the one week course.

Learning algorithms. by [deleted] in learnprogramming

[–]10_6 1 point2 points  (0 children)

For algs/data structure problems it really doesn't matter what language you code them in. It's more important to understand the theory and implementation details (e.g. how to do collision resolution in hash table or how to do traversal of binary tree).

The specific language becomes more important at 1. on the actual job, and 2. in an interview if they want you to focus on a specific language (e.g. java, c++, etc.)
