If the question says that the difference has to be absolute, then sorting the array and finding the adjacent difference is the most appropriate solution. But if the question says finding the smallest difference out of all the pairs from an array i.e min_diff can be less than 0, then we can find it with the following code.
MIN_DIFF(ARRAY){
MAX_ELEMENT := FIND_MAX(ARRAY) //O(n)
MIN_ELEMENT := FIND_MIN(ARRAY) //O(n)
return MIN_ELEMENT  MAX_ELEMENT
}
This this runs in O(n) time and O(1) space.
