Write a program to print in order all the divisors of a given number.
Input
Input consists of several cases, each with a natural number n between 1 and 109.
Output
For every n, print the divisors of n in increasing order.
Observations
Hint
Every divisor smaller than the square root of n has a corresponding divisor greater than the square root of n. It could be useful to make two loops, one for “small” divisors, and another for “large” divisors.
Input
200 6 1 100 999999998 999999937
Output
divisors of 200: 1 2 4 5 8 10 20 25 40 50 100 200 divisors of 6: 1 2 3 6 divisors of 1: 1 divisors of 100: 1 2 4 5 10 20 25 50 100 divisors of 999999998: 1 2 691 1382 723589 1447178 499999999 999999998 divisors of 999999937: 1 999999937
