Solve

At prime folder:

Run test case

rspec spec/prime_spec.rb

Check output for problem 1

Find the sum of all the primes below 2 million

ruby output/sum_of_all_primes.rb

Check the time find the sum of all the primes below 2 million

time ruby output/sum_of_all_primes.rb

Check output for problem 2

Find prime, below one million, can be written as the sum of the most consecutive primes

ruby output/sum_of_most_consecutive_primes.rb

Check the time find prime, below one million, can be written as the sum of the most consecutive primes

time ruby output/sum_of_most_consecutive_primes.rb
