//Parameters: an array of at least two elements, both of which are numbers

//Return value: a positive number like 10, 7, 3, 1

//Example: [-10, 0] => 10 because |-10 - 0| = 10

//Psuedocode: 

//for each element, compare it to all the other elements and find the absolute difference

//add each absolute difference to an array

//return the minimum of the array
