sum-of-two-lowest-positive-integers.cs

// 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.
