Cs50 algorithms reddit It's not a bad course, and if you have one and only course to take to learn basic cs and programming, it's the best at that. Watch the lectures, do the problems and make sure you stay on pace each week and finish the whole course. I'll have to think on this but I think this is the path that's going to lead to understanding. Starting with some basic algorithms to figure out the amount of change due, the material quickly accelerates, and by Problem Set 3, students are making a version of the classic arcade game Breakout. An undergraduate course in discrete mathematics is assumed, and students should be comfortable analyzing the asymptotic running time of algorithms. If you submit and receive a score of at least 70% on each of this course’s problem sets and labs as well as its final project, you will be eligible for a free CS50 Certificate like the below. I think I get it - don't compare sort algorithms against each other but rather against the size of the data set against another data set with the same algorithm and how the algorithm performs in each situation. You will only be introduced to certain Data structures (Linked List, Hash Tables, Binary Search Tree IIRC)& for Algorithms, the lecture only introduced to Linear & Binary Demanding, but definitely doable.
