Consider the following function prototype: double tryMe(double, double); Which of the following programming statements is valid and will not generate a compiler error? You should assume that all variables, parameters, and even the function itself are all declared and defined correctly.

A name declared within a local scope (a variable declared inside of a function, for example) cannot be seen by any other function declared outside of its local scope. This is done in order to prevent naming conflicts and preserve the black box nature of how the function implements itself to facilitate the computer science concept of abstraction through information hiding.

Mary wants to run a 25-mile marathon. When she attempts to sign up for the marathon, she notices the sign-up sheet doesn’t directly state the marathon’s length. Instead, the marathon’s length is listed in small, different portions. Help Mary find out how long the marathon actually is. Return true from your is_a_marathan function if each leg of the marathon listed element by element in the cells of the array adds up to be exactly 25 miles long, otherwise, return false. Hint: You only need to add up the elements in the array to decide if the sum of all of the numbers in the array add up to 25 and return a true from your is_a_marathan function definition. You only need to write the function definition for the is_a_marathan function. You do not have to write a main method or handle the function call itself just the function definition only. Examples marathonDistance([1, 2, 3, 4]) ➞ false marathonDistance([1, 9, 5, 8, 2]) ➞ true marathonDistance([-6, 15, 4]) ➞ true Notes Items in the array will always be integers. Items in the array may be negative or positive, but since negative distance isn’t possible, find a way to convert negative integers into positive integers. Return false if the arguments are empty or not provided.
