Positive Sum

This document contains code written in the Kotlin programming language. It defines a sum function that takes an array of integers and a lambda function as parameters. The lambda function specifies how to combine (add) the accumulator and each element. It also defines a getLambda function that returns a sample lambda. The main function serves as the entry point but does not contain any additional code.
