[Challenge] Sum Arrays

Sum Arrays

Given an array of values, return the sum of the values.

Business Rules/Errata

• Input must be an array.
• The array may be nested more than one level.
• All values must be integers.
• Solutions shall not use built in methods to flatten the array to one-dimension.

Examples

One dimension:

sum_of_array([1,2,3,4,5]) => 15

Two dimensions:

sum_of_array([1,2,[1,2,3],4,5]) => 18

n dimensions:

sum_of_array([1,[1,2,[3,4],5],[6,7]]) => 29

Ah man, this one is really hard! (Assuming you use a statically typed language that doesn't natively support arbitrarily nested arrays).

That's an interesting point. Perhaps it's for later or for a subset of languages.

This is a true challenge

It should be fun!
