-- Exercise 1

-- We need to first find the digits of a number.
-- Define the functions

--   toDigits :: Integer -> [Integer]
--   toDigitsRev :: Integer -> [Integer]
--   toDigits should convert positive Integers to a list of digits. (For 0 or
--   negative inputs, toDigits should return the empty list.) toDigitsRev
--   should do the same, but with the digits reversed.

## equilibrium_index
A zero-indexed array A consisting of N integers is given.

An equilibrium index of this array is any integer P such that 0 ≤ P < N
and the sum of elements of lower indices is equal to the sum of elements of higher indices,

i.e. A[0] + A[1] + ... + A[P−1] = A[P+1] + ... + A[N−2] + A[N−1].

Sum of zero elements is assumed to be equal to 0. This can happen if P = 0 or if P = N−1.
For example, consider the following array A consisting of N = 7 elements:
A[0] = -7   A[1] =  1   A[2] = 5

## falsy_values.js
var sum = function sum(x, y) {
  if (!x) {
    x = 200;
  }

  if (!y) {
    y = 300;
  }

  return x + y;
