Too Long; Didn't Read
The article is the article I wish I had read when I started coding. I will dive deep into 20 problem-solving techniques that you must know to excel at your next interview. The last section includes a step-by-step guide explaining how to learn data structures and algorithms, with examples. I have grouped these techniques in: Two Pointers, Recursion and Sorting and searching. I strongly recommend you code your solution and see if it passes the tests. I have left links to all of the exercises.
