Arrange the digits 0 through 9 so that the number formed by the first (leftmost) digit is divisible by 1, the number formed by the first 2 (leftmost) digits is divisible by 2, the number formed by the first 3 (leftmost) digits is divisible by 3, and so forth. What is the 10-digit number? If you were only allowed to use the digits 1 through 9, what would the 9-digit number be?
