Write a regex pattern to match strings of the form a-zA-Z0-9.
A regex pattern that would match strings composed only of characters from the Latin alphabet (both uppercase and lowercase), and numbers from 0 to 9, is: `^[a-zA-Z0-9]+$`

Explanation:
- The `^` and `$` symbols indicate that the match should start from the beginning (`^`) and finish at the end (`$`) of the string, respectively.
- The `[a-zA-Z0-9]` expression inside square brackets indicate a character set. This means it will be matching a single character that is either a lowercase letter between `a-z`, an uppercase letter between `A-Z` or a number between `0-9`.
- The `+` indicates that the character set should be matched one or more times, making it possible to match the entire string.
