programming-problems
This is basically just a place for me to put problems I feel like solving for fun. But it doubles as exercises for programmers!
Download, Fork & Install
git clone https://github.com/candyapplecorn/programming-problems.git && \
cd programming-problems && \
git checkout -b `whoami` && \
npm install
Instructions
There are two branches, master and answers. Master has problems to be solved in test/. The files inside test/ all have spec.js as their file extensions; they're jest tests! Each test will import (in Javascript / Nodejs, require) its associated file from the lib/ folder and then run tests and assertions against the imported code. Your task is to write code in lib/ to make tests in test/ pass. Do not edit code inside of test/, unless you want to add additional tests & assertions.
Running tests
To run tests, simply type:
npm run test --watch
The --watch flag tells the test runner (Jest) to re-run its tests whenever file changes are detected (whenever a file is saved).
Answers
There's a branch called answers which has solutions for each problem. On that branch npm run test should pass all tests. To see that branch, simply check it out:
git checkout answers && \
npm run test
Git help
Remember, you can see all your local branches by typing git branch. You can switch to any of those branches by typing git checkout <branchname>. You might get an error when trying to check out a branch, saying you need to commit your uncommitted changes, or something similar. If you get this error, simply type git status to see all the unadded files and uncommitted changes. Either add and commit them to your current branch with git add <files> and then git commit -m '<message goes here>', or temporarily stash them with git stash. If you decided to temporarily stash your work, don't forget it's stashed! It won't show up as a commit in your commit history (to see your commit history type git log); to get your stashed changes back, simply type git stash pop. Again, be careful with git stash - it's easy to get mixed up!
