The sum of the numbers from 1 to n can be performed recursively as follows: The sum from 1 to 1 is 1. The sum from 1 to n is n more than the sum from 1 to n-1. Write a int-function named sum that accepts an int parameter, n, and recursively calculates and returns the sum of the numbers from 1 to n. .
