Number Maze

Write a program that computes the minimum number of steps required to go from a starting number to an ending number given the following rules:

  • A number may be doubled
  • You may add 2 to a number
  • A number may be halved if it is even

Example:

  • 2 → 9
  • Potential steps to get from 2 to 9:
  • 2, 4, 8, 16, 18, 9 (This can be done twice, doubling 2 or 2 + 2)

Tips for all you need to do to set up a new Mac
  • Install homebrew with /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
  • Install Oh My Zsh with sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
  • Install Clojure Tools Deps with brew install clojure/tools/clojure
  • Install babashka
  • Install Docker for Mac
  • Fix desktop switching at System Preferences... > Keyboard > Shortcuts > Mission Control. Note that this is NOT in Mission Control. Map Mission Control, Move left a space, and Move right a space to ctrl+opt+X vs. ctrl+X as ctrl+X will intefere with slurp and barf.
  • Change terminal shell to homebrew them at Terminal > Preferences > Profiles > Homebrew, then click "Default" at the bottom of the left side panel. Also, change the font size to something larger like 24pt.

Compelling questions
  • What is the purpose of tests?
  • What is the purpose of documentation?
  • What is the opposite of complex?
  • Complete the quote by Edsger W. Dijkstra: "blank is the prerequisite for reliability" (Simplicity)
  • Does using a consistent language give you more immediate access to a problem?
  • How long should it take a person to get "up to speed" on:
    • a codebase?
    • a project?
  • a domain?

  1. Never do hardware
  2. Never do infrastructure
  3. Understand the problem
  4. Start with a press release
  5. Always be demo ready
  6. State features as "I can..."
  7. Paying down technical debt is not a feature and should not be a goal
  8. Data flows from the left, money flows from the right
  9. More prose, less code
