Create a function that takes a list of numbers and returns the sum of the two lowest positive numbers.

Examples

sum_two_smallest_nums([19, 5, 42, 2, 77]) ➞ 7

sum_two_smallest_nums([10, 343445353, 3453445, 3453545353453]) ➞ 3453455

sum_two_smallest_nums([2, 9, 6, -1]) ➞ 8

sum_two_smallest_nums([879, 953, 694, -847, 342, 221, -91, -723, 791, -587]) ➞ 563

sum_two_smallest_nums([3683, 2902, 3951, -475, 1617, -2385]) ➞ 4519
