kkeppel / primes-test Goto Github PK

Thank you for reviewing my code test! My objective was as follows:

• Write a program that prints out a multiplication table of the first 10 prime numbers.
• The program must run from the command line and print one table to STDOUT.
• The first row and column of the table should have the 10 primes, with each cell containing the product of the primes for the corresponding row and column.
• Consider complexity. How fast does your code run? How does it scale?
• Consider cases where we want N primes.
• Do not use Prime class from stdlib.
• Write tests. Try to demonstrate TDD/BDD.

To run the script, please first do a bundle install to acquire RSpec for testing.

Navigate to the project directory and run ruby ./prime_test.rb. You will be asked to input a number for the primes count. Pressing Enter will run the script for 10 primes by default. Test it out with bunches!

rspec spec/prime_test_spec.rb will run the tests.
