Coding challenge
Update: I posted a wrap-up here.
Here is an interesting coding challenge: write a counter function that counts from 1 to max but only returns numbers whose digits don't repeat.
For example, part of the output would be:

* 8, 9, 10, 12 (11 is not valid)
* 98, 102, 103 (99, 100 and 101 are not valid)
* 5432, 5436, 5437 (5433, 5434 and 5435 are not valid)
Also:
* Display the biggest jump (in the sequences above, it's 4: 98 -> 102)
* Display the total count of numbers
* Give these two values for max=10000

Post your solution in the comments or on your blog. All languages and all approaches (brute force or not) are welcome.

I'm curious to see if somebody can come up with a clever solution (I don't have one)...

Here is my revised JavaScript solution (that actually works this time).

Carol James and the BC NDP are going on about how the gas tax is unfair and otiose. I say its a step in the right direction.

1. The NDP constantly says that Gordon Campbell should "tax the big polluters instead". Well guess what? Automobiles are one of the largest, if not the largest in B.C.

With both the video tutorials, and the in depth guide, verily, there are no reasons to complain. If you are at least fairly competent with a computer, or have played Pandemic or other games, you probably don't need to watch the first video.
