Solving Problem 1 of Project Euler

As I understand it,, a project made by Google engineers, is about adaptive learning. Since there is a lot of merit in such an approach and since I am already familiar with such an approach from Microsoft’s exams, I thought I’d try it.

Well, it is still in beta and not impressive, but I wanted to show’s response of my attempt to solve Problem 1 of Project Euler that features.

Before I show you’s response, I would like to state Problem1 of Project Euler:

Find the sum of all multiples of 3 or 5 below 1000.

I would also like to give you the Haskell one-liner I used to solve it:

sum [x | x <- [1..999], (x `mod` 3 == 0 || x `mod` 5 == 0)]

and the result, which is 233168.

Below is the screenshot from my use of WinGHCi:


And here is my use of’s dialog driven approach:


Although it seems that understands Haskell, it doesn’t. In fact it wants Python code in order to be able to run it. You can put any invalid (Haskell or other) code there and the response will be the same. So, is very unimpressive at its present form. And I do not have high hopes that it will impress me in the future. We’ll see if I am proven correct or incorrect in the future.

Finally, if you want to calculate the same thing using Excel, put the numbers 1 to 999 in the first column from cell A1 to cell A999, and put the formula


in the cell B1 and copy it all the way down including cell B999. Sum the second column’s cells and the result will be 233168.
