/**
 * Create a function that returns the sum of the two lowest positive numbers given an array of minimum 4 positive
 * integers. No floats or non-positive integers will be passed;
 * 
 * For example, when an array is passed like [19, 5, 42, 2, 77], the output should be 7;
 *      [10, 343445353, 3453445, 3453545353453] should return 3453455.
