Project Euler 5

Ok. I have to admit this took more time in getting there.

I did not want to brute force the answer and I did not remember how GCD is calculated.

I do like that looping – its sort of fancy – but am afraid I wont be using it any time soon, if ever.

After a while I had time to play around with Project Euler again.

This is again a pretty straightforward solution. The ruby value from this exercise is that I found ruby does not have increment or decrement operator, which is a departure from C and Java. The argument for this design decision is here.

The only hint I think may be useful for someone just stuck at what looks like a pretty good palindrome is that look at your loop again may be there is a greater number that you never reached because you broke the loop.

By the way, this is a great resource for ruby newbies like me!
