This example comes from Steve Eddins' blog: Learning Lessons from a One-Liner
Write a function that takes a list or array of numbers as input and return the largest number that is adjacent to a zero.
Example:
Input x = [1 5 3 0 2 7 0 8 9 1 0] Output y is 8

Two more tests:
1. Input x = [-4 -2 0 -4 -1 0]
Output y is -1.
2. Input x = [-9 -3 0 0 -5 0 -2 -1]
Output y is -2.
Good comment, Gaik. A lot of solutions (including mine) will break with two consecutive zeros.
Why: "Input x = [-9 -3 0 0 -5 0 -2 -1] Output y is -2."???
Output should be 0. It doesn't say anywhere that the number adjacent to a zero must be nonzero!
