Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file lib/collect_factors. To experiment with that code, run bin/console for an interactive prompt.
TODO: Delete this and the text above, and describe your gem
Add this line to your application's Gemfile:
gem 'collect_factors'
And then execute:
$ bundle
Or install it yourself as:
$ gem install collect_factors
Run factors.rb in the command line (ruby factors.rb)
Input: Given an array of integers
Output: Output each integer in the array and all the other integers in the array that are factors of the first integer.
Example:
Given an array of [10, 5, 2, 20], the output would be: { 10: [5, 2], 5: [], 2: [], 20: [10,5,2] }
Additional Questions:
1.What if you were to cache the calculation, for example in the file system. What would an example implementation of the cache look like? By cache I mean, given an array input, skip the calculation of the output if you have already calculated the output at least once already.
Answer: The implementation of a cache uses cache_response to store and access the factorizations calculated from the given array. In the event of duplicates, cache_response would speed up the method considering that some of the calculations would be skipped. In my specific case, the use of caching(cache_response) did not affect the run time since the arrays were composed of unique integers.
2.What is the performance of your caching implementation?
Answer: The implementation, which uses ruby dictionaries (hash maps), has a linear run time. The example uses arrays that don’t have any duplicates. If it does have eb=ven in that case the hash map will help the cache response method to return faster response, as we are storing result in key value pairs.
After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
