Kata

Description

For this Kata you will be given an array of numbers and another number n. You have to find the sum of the n largest numbers of the array and the product of the n smallest numbers of the array, and compare the two.

If the sum of the n largest numbers is higher, return "sum"
If the product of the n smallest numbers is higher, return "product"
If the 2 values are equal, return "same"

Note The array will never be empty and n will always be smaller than the length of the array.

Example

sumOrProduct([10, 41, 8, 16, 20, 36, 9, 13, 20], 3) // => "product"

productOrSum [10, 41, 8, 16, 20, 36, 9, 13, 20] 3 -> Product

sum_or_product(&[10, 41, 8, 16, 20, 36, 9, 13, 20], 3) // => "product"

sum_or_product([10, 41, 8, 16, 20, 36, 9, 13, 20], 3) # => "product"

sumorproduct([10, 41, 8, 16, 20, 36, 9, 13, 20], 3) # => "product"

Explanation

The sum of the 3 highest numbers is 41 + 36 + 20 = 97

The product of the lowest 3 numbers is 8 x 9 x 10 = 720

The product of the 3 lowest numbers is higher than the sum of the 3 highest numbers so the function returns "product"
