"""Create a function that returns the sum of the two lowest positive numbers
given an array of minimum 4 integers. No floats or empty arrays 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.

Hint: Do not modify the original array. """
