AHSME 1991 Problem 26

    An nn-digit positive integer is cute if its nn digits are an arrangement of the set {1,2,...,n}\{1,2,...,n\} and its first kk digits form an integer that is divisible by kk, for k=1,2,...,nk = 1,2,...,n. For example, 321321 is a cute 33-digit integer because 11 divides 33, 22 divides 3232, and 33 divides 321321. How many cute 66-digit integers are there? (A) 0(B) 1(C) 2(D) 3(E) 4\text{(A) } 0 \text{(B) } 1 \text{(C) } 2 \text{(D) } 3 \text{(E) } 4
