Lets populate our dp array from the above solution, working in a bottom-up fashion. Usage: This technique helps us solve problems that involve a list of sorted arrays. I liked the way Grokking the coding interview organized problems into learnable patterns. You can check out Grokking Dynamic Programming Patterns for Coding Interviews here. For example, when you calculate factorial, the base case is factorial which is 1, you mean you know the answer so you can directly return it and from there onwards recursion will unroll and calculate factorial for the given number. The second question below encompasses the first one though. If you like books, I also suggest you take a look at the Grokking Algorithms by Aditya Bhargava. In each pattern, youll first learn a recursive brute-force solution, which is actually the best way to start solving a DP problem. Other courses developed by the same team can be found on their website. Given two intervals ('a' and 'b'), there will be six different ways the two intervals can relate to each other: Usage: Use this technique to solve array problems where the input data lies within a fixed range. and take a look at some coding problems which can be solved using Dynamic programming. The fact is, Dynamic Programming (DP) problems can be some of the most intimidating on a coding interview. Even when its clear that a problem can be solved using Dynamic Programming (which is also difficult), it can be challenging to even know where to start on the solution. Thats because the creators of this course had one goal in mind for programmers: the ability to map a new problem to an already known problem.
