Brain Teaser #75
Can you find the largest number possible containing any of 9 of 10 digits, considering 0 also a number, that is divisible by 11 without a reminder?

The wording is a bit strange, but I think I got it. I did a brute force attack on this problem. Starting at 999999999 and decrementing by 1 each time, I did a modulus 11 and checked if the result was 0. Here is what I got:
999999990 or if you can only use each digit once it is 987652413 |
