The Biggest File

You have a few saved essays and want to find the longest one.

Write longest_file(paths). paths is a list of file names. Read each file and return the name of the file that holds the most characters.

If two or more files tie for the most, return the one that comes first in paths.
paths always has at least one name in it.
Use with to open each file.

The starter has a make_file(path, text) helper that creates test files. Leave it as it is.

Examples

paths = [make_file('a.txt', 'hi'), make_file('b.txt', 'hello'), make_file('c.txt', 'hey')]

returns 'b.txt'

paths = [make_file("lf_a1.txt", "short"), make_file("lf_a2.txt", "much longer text")]

returns 'lf_a2.txt'

paths = [make_file("lf_b1.txt", "same"), make_file("lf_b2.txt", "size")]

returns 'lf_b1.txt'
