Matchstick factory Challenge

A matchstick factory has to put n matchsticks in boxes. The factory has the following three types of boxes:

A big box holds 50 matchsticks A medium box holds 20 matchsticks A small box holds five 5 matchsticks The boxes can’t have fewer matchsticks than they can hold; they must be full.

Implement the boxes/1 function in the MatchstickFactory module. The boxes/1 function returns the number of boxes of each size needed to accommodate all the matchsticks and the number of remaining matchsticks as a map (The map is included in the started code). It should work like this:

Pre-Reqs

Brew Package Manager

In your command-line run the following commands:

brew doctor
brew update

Solved that problem running these first:

sudo apt update sudo apt install git zsh -y Then the curl:
