Angle-bracketed references are a Nix anti-pattern, and thankfully this repository enforces this as a standard. TL;DR: - Drop angle-bracketed references - Change `briefcase` -> `users.wpcarro` - Fix any resulting regressions - Fix //users/wpcarro/tools/simple_vim - Mark //users/wpcarro/boilerplate/typescript and related projects as broken - drop .skip-subtree file, enabling depot CI Change-Id: I7153cbabafa617bfd6b199370cbec65cb75441f6 Reviewed-on: https://cl.tvl.fyi/c/depot/+/4325 Tested-by: BuildkiteCI Reviewed-by: wpcarro <wpcarro@gmail.com> Reviewed-by: tazjin <mail@tazj.in> Reviewed-by: grfn <grfn@gws.fyi> Autosubmit: wpcarro <wpcarro@gmail.com> |

Semiprimes Service
Introduction
A composite is a number containing at least two prime factors. For example:
15 = 3 × 5
9 = 3 × 3
12 = 2 × 2 × 3
There are ten composites below thirty containing precisely two, not necessarily
distinct, prime factors: 4, 6, 9, 10, 14, 15, 21, 22, 25, 26. Let’s call such
numbers Semiprimes.
Task
- Write a module which provides a function to tell whether a given number,
N, is a semiprime.Nwill be less than 100,000 - Please implement an API (RESTful or GraphQL) to factor a given number into two prime numbers if it’s a semiprime, otherwise, return an error message.
Stretch Goals
- Handle the invalid inputs.
- Support batch requests: i.e. users could provide 100 numbers, and the API return the answer for all.
- Considering this module will be used by a long running service, could you optimize it to give answers faster?
Usage
To run the application you'll need to have elixir installed. Assuming elixir
is already installed, consult the following steps to start the application:
$ cd server
$ mix deps.get
$ iex -S mix
Now open a web browser and visit http://localhost:8080!
