RUBY: For the following code,

1)I need a code that returns the sum of the elements of the arr array

2)I need a code that return the sum of the two largest elements of the array

-For an empty array it should return zero

-For an array with just one element, it should return that element

3)Lastly I need the code that will return if any two elements in the array of integers (arr) sum to the integer n.

-sum_to_n?([], n) should return false for any value of n, by definition.

-Any single element array should return false

Will put code here
