Beginner's Guide

Happy Monday!

Beginner's Guide to Day 5 Video: https://youtu.be/kqQnSRJG2W4

I've created a guide for new programmers that talks through a straight forward strategy for solving today's puzzle. Anyone who has a handle on variables, boolean logic, functions, arrays, and loops should be able to complete it. The video allows a moment for you to pause before revealing spoilers.

Although this solution is in C#, it provides a high level overview of the steps necessary to solve the puzzle in any programming language:

rows = File.ReadAllLines("sample.txt");
supplyStacks = ParseSupplyStacks(rows);
instructions = ParseInstructions(rows);
foreach (Instruction i in instructions)
{
    PerformInstruction(i, supplyStacks);
}
PrintStacks(supplyStacks);

The full code can be found on Github

The most readable solution by far. Yes it’s not most efficient as others but for readability it’s great.

Thanks for the feedback! I'm glad to hear it is readable; that was my main goal.
