Implement a factor function that takes an int as an argument and returns a vector of ints containing the factorization of the number passed. As an example, calling factor() passing 1050 will return a vector containing {2, 3, 5, 5, 7}.
Then, implement main() to read an int, pass that int to factor(), and print the resulting vector.
Example:
1050 = 2 * 3 * 5 * 5 * 7
