The questions are not so much about problem-solving as they are about working with data structures. Description. It’s my least favorite site among the three for practicing and learning, and I didn’t spend a lot of time on it. You just have to dive into it head-first — start writing code, debugging code, and reading other people’s correct code to figure out where, how, and why you went wrong. Some questions which I thought were great: Unlike data structures questions, the focus here isn’t so much about working with or manipulating data structures, but rather, how to do something. Data structures are the ways in which data is arranged in computers memory. Presentation Mode Current View. For instance: You get the idea.

At a minimum, algorithms require constructs that perform sequential processing, selection for decision-making, and iteration for repetitive control. The “searching in a rotated sorted array” problem presents a twist on binary search. I like how it provides code snippets in various languages, usuallyC++, Java, and Python, which you can copy and paste into your IDE to step through line-by-line. Dynamic programming is definitely something that should be reserved for more advanced textbooks (with maybe, at best, an introduction to the subject at this level).
