DATA STRUCTURES LEARNING TOOL

This application helps to solve the problem of learning new terminology by using a spaced-repetition algorithm learning technique that incorporates increasing intervals of time between subsequent review of previously learned material in order to exploit the psychological spacing effect. The application allows individual users to create their own account and tracks their progress through the content. Also included is a reset button to allow the user to start back at the beginning of the content at any time and reset their progress.

Params:

• user.id: string

Request

{
  "user.id": string
}

Response

{
    "question": "_________ is a method of solving problems that involves a function calling itself.",
    "answer": "recursion",
    "explanation": "In each call, it breaks down the problem into smaller and smaller subproblems until you get to a small enough problem that it can be solved trivially. You can think of it as the process of defining a problem (or the solution to a problem) in terms of (a simpler version of) itself. It may be applied to several data structures and algorithms to solve problems, but by itself is not a data structure or an algorithm, it is a concept.",
