Project Euler

For those of you looking for some sort of challenge I found a cool site which will test your maths, logic and programming skills:

Have Fun :)

This really is quite fun. I just finished the first one, and I begin to be addicted.

Second done. (Problem 6)

Very interesting site, I have to recommend it. I can spend so many time over there and forget work... uh? I should get back to work. :)

I got 4 of the probs done, but the 1st one just doesn't want to work for some ungodly reason, stupid multiples... pah!

ps, There IS a use for StrReverse!

I've done 7 of them now, and for the first one check this (I had this problem): They say "Find the sum of all the multiples of 3 or 5 below 1000."

You only have to count 1 time 15 and not 2 times.

I've done 50 problems :p

Checking for multiples is simple. Just loop through all the numbers 1 to 1000. If the number Mod multiple = 0 then the number is divisible by that number.

dude, i love you. i couldnt figure out how to check if a number is divisble. thanx for showing me this time draining site too. ;)

For checking if a number is divisible I used

If i / Multiple = Int(i / Multiple) Then

This should prove to be faster over a long run:
If this Mod that = 0 Then MsgBox "Multiple"

You don't need a computer for that one... you can solve it with pen and paper in a couple of minutes. :)

I did it in Excel, I think it's less time consuming. :p

I did #8 and #11 jsut by looking at it for a while, not that hard. :)
