One-off golang project to solve a coding challenge:
- Take the sample string posted on a web page
- Get frequency counts of characters
- Order characters by frequency
- And (hopefully) reveal the secret word
I chose golang for the project with the hopes of learning more about concurrency with goroutines and channels. That didn't work out. Instead, I ended up getting experience with golang's interfaces, and a couple new packages:
This repo also contains some basic unit tests that can be run with go test.
My results are published on my Docker Hub account.
Give it a pull with docker pull jkaplon/str-freq-sort.
Give it a try with docker run --rm --name str-freq-sort jkaplon/str-freq-sort.
In the process, I built a hacky-but-useful development docker image with auto-reload for Go web apps. The development branch contains the alternate Dockerfile with the auto-reload setup.
