Programming Praxis

We have today another exercise from our limitless supply of interview questions:

You are given two arrays of integers, where the integers do not repeat, the two arrays have no common integers, and both arrays are sorted in ascending order.

Let x be any integer in the first array and y be any integer in the second array. Find min(abs(x − y)); i.e., find the smallest difference between any integers in the two arrays.

Your task is to write a program to find the smallest difference. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
