Implement a function that finds the first position of any characters from a set in a given string. For example, first in set("spring", "aeiou") returns 3 because 'i' occurs in the set "aeiou" and the preceding characters do not. If there is no match, return -1. Use multiple return statements. As soon as you have computed the answer, return it.
