In my attempt to learn (Iron)Python out in the open, here’s my solution for Project Euler Problem 12. As always, any feedback is welcome. # Euler 12 # http://projecteuler.net/index.php?section=problems&id=12 # The sequence of triangle numbers is generated by adding # the natural numbers. So the 7th triangle number would be # 1 + 2 + 3 + [...]

In my attempt to learn Ruby out in the open, here’s my solution for Project Euler Problem 53. I first attempted to solve this problem using the Ruby combinations libraries. That didn’t work out so well. With a second look at the problem, the provided formula ended up being just the thing to solve the problem effectively. [...]
In my attempt to learn Ruby out in the open, here’s my solution for Project Euler Problem 52. Compared to Problem 51, this problem was a snap. Brute force and pretty quick… As always, any feedback is welcome. # Euler 52 # http://projecteuler.net/index.php?section=problems&id=52 # It can be seen that the number, 125874, and its double, # 251748, [...]
In my attempt to learn Ruby out in the open, here’s my solution for Project Euler Problem 51. I know I started back up with Python this week, but I have three more Ruby solutions in the hopper and I wanted to share. For the record, Project Euler 51 was the second hardest Euler problem for me [...]
In my attempt to learn (Iron)Python out in the open, here’s my solution for Project Euler Problem 10. As always, any feedback is welcome. # Euler 10 # http://projecteuler.net/index.php?section=problems&id=10 # The sum of the primes below 10 is 2 + 3 + 5 + 7 = 17. # Find the sum of all the primes below two [...]
