The idea is to simply store the results of subproblems, so that we do not have to re-compute them when needed later. Code an algorithm for a game consisting of two players. As understanding those concepts requires much more effort, this list below only serves as an introduction. Interview questions from the most popular companies in the IT industry are taken as examples to illustrate the five factors above. Dynamic Programming is an algorithmic paradigm that solves a given complex problem by breaking it into subproblems and stores the results of subproblems to avoid computing the same results again. Dynamic Programming Interview Questions Page: 1 2 3. The fact is, Dynamic Programming (DP) problems can be some of the most intimidating on a coding interview. Until you’re sure about the program, it’d be better to not change the settings. Being in a mindset required for an upcoming event is like winning half the battle. Even when it's actually clear if a problem can be solved using DP (which it rarely is), it can be pretty challenging to even know where to start on the solution.
