Find One Two Three
In lists, you often search for a whole pattern, not just one value, such as a sequence of actions or a code combination. Write a function array123 that takes a list of numbers nums and returns True if the numbers 1, 2, and 3 appear next to each other in that exact order. If no such triple exists, return False.
