misc code puzzle solutions

a place for me to stash random code puzzle solutions, like:

• advent of code | https://adventofcode.com
• everybody codes | https://everybody.codes
• leetcode https://leetcode.com
• project euler | https://projecteuler.net

scripts

NOTE: if you don't have yarn installed, you can replace yarn below with npm run, eg npm run new aoc 2028 1 some description here

yarn new aoc <year> <day> will scaffold the solution for year/day (day 1-25 only)

you may need to run yarn fixNew to give the script permissions.

yarn new sandbox <number> will scaffold a sandbox the given number (1-999 only)

you may need to run yarn fixNew to give the script permissions.

yarn test will run all tests (only shows detail for failed tests)

to run only a specific set of tests, use .only modifer on any level of mocha block, eg

describe.only('the set of tests I want to run now', () => {
    // tests here
})

yarn test:verbose will run all tests with per-test spec displayed (even passing tests)

yarn notes will grab important comments from code

example output:

>> yarn notes

> @ notes /path/to/root
> ./node_modules/notes/bin/notes

* /path/to/utils/js/scaffoldCurrentDirectory.js
