* This robot won 2nd place in an internal Robocode tournament. The 1st place had a complex algorithm with over 1k LOC, and most other participants had over 600 LOC ;)

# Usage: `ruby calculate_cpf_digits.rb "123456789"`

cpf = ARGV[0]
cpf_array = cpf.split("").map(&:to_i)

def calculate_digit(base_array:)
  # Constants
  divisor = 11 # Constant, fixed number
  weighted_array = [10, 9, 8, 7, 6, 5, 4, 3, 2] # Digits, starts with 10 and decrements by 1

# 1. Configure your Swift Package scheme to collect code coverage for "all targets" - NOT "some targets"
# 2. Test your Swift Package using either `xcodebuild test`, which should generate a `.xcresult` file.
# 3. Convert that `.xcresult` file into a `.json` file using:
#    ```sh
#    $ xcrun xccov view --report --json #{path_to_xcresult_file} > #{xccov_json_report}
#    ```
# 4. Lastly, strip out the targets that you're not interested using this method.
#    
# Note 1: This code considers you only want to keep 1 of the targets.
# Note 2: The resulting json file will replace/override the existing one without any warning.

Commit Message Guidelines

These guidelines are based off of this guide. Some of the key takeaways, plus some other opinionated guidelines:

1. Clarity is key: a commit should be clear even to a viewer who doesn’t have the full context in which it was made.
2. Start your commit message with a verb, and use sentence case capitalization.
3. Use the imperative verb when writing a commit message (see the link above if you don’t know what that means). Example: "Fixed" → "Fix"
4. Commit things that make sense to be grouped in a single commit. Ask yourself "does it make sense for someone to cherry pick this single commit? Is there something missing in it, or something extra that the person wouldn't need?" - if you do that, you'll end up aiming for 1 commit per fix or feature, which makes the codebase cleaner.
5. Test what you are fixing before committing. Only commit what you’ve tested and are sure that is good to go. This avoids unnecessary comm

Is this a scam?

Hah, I won't waste much time explaining this so: tl;dr: no, it's not a scam.

There's no such thing as free money, so the money being given out here is actually a function of:

1. Time
2. You being probably an active Open Source contributor (after all those years, you're finally being rewarded in cash! Or, sorta cash, haha)
