brute force approach

Generate all possible 4-digit codes with no repeat numbers ($10*9*8*7 = 5040$) and filter these so that each one must contain at least one digit from every provided guess. The resulting list has only one entry: 4-3-2-1.

def bruteForce(guesses: List[List[Int]]): List[Int] =
  // first, generate the candidate solutions:
  // all possible 4-digit PINs without repeat digits.
  val all = for
    a <- 0 to 9
    b <- 0 to 9 if b != a

CDK notes

Notes on building a small application (two lambdas and a step function state machine) with the CDK (TypeScript).

directory structure

cdk init can only be run in an empty directory. The name of this directory is used throughout the generated code, notably as the name of the generated stack. It seems like the intention is to use the root directory of the project for the CDK code as well as any other source code. I preferred to separate the CDK code from Scala, so I put it into its own subdirectory that was ultimately named cdk, but when running cdk init I temporarily gave it the same name as my project so the generated stack name made sense (e.g. MyProjectStack instead of CdkStack).

constructs

CDK applications are made by composing constructs. A construct is a representation of an AWS Resource at varying levels of abstraction. Some are auto-generated and therefore as low-level as CloudFormation itself, others provide a
