Given the first line of a comma-separated values (CSV) file, return an array containing the headings.

• The first line of a CSV file contains headings separated by commas.
• Remove any leading or trailing whitespace from each heading.

--hints--

get_headings("name,age,city") should return ["name", "age", "city"].

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_headings("name,age,city"), ["name", "age", "city"])`)
}})

get_headings("first name,last name,phone") should return ["first name", "last name", "phone"].

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_headings("first name,last name,phone"), ["first name", "last name", "phone"])`)
}})

get_headings("username , email , signup date ") should return ["username", "email", "signup date"].

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_headings("username , email , signup date "), ["username", "email", "signup date"])`)
}})
