Using python and for loops write a function fewest_characters that takes a single argument, a list of strings, and returns the string that contains the fewest characters. In the case of a tie, return the leftmost string with the fewest characters. If the list is empty, return the empty string.

Examples:

>>> fewest_characters(["Arizona", "California", "Texas", "Utah"]) 'Utah' >>> fewest_characters(["Pear", "Apples", "Oranges"]) 'Pear'
