--description--
Given a string of numbers separated by various punctuation, return the largest number.
- The given string will only contain numbers and separators.
- Separators can be commas (
","), exclamation points ("!"), question marks ("?"), colons (":"), or semi-colons (";").
--hints--
largest_number("1,2") should return 2.
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(largest_number("1,2"), 2)`)
}})
largest_number("4;15:60,26?52!0") should return 60.
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(largest_number("4;15:60,26?52!0"), 60)`)
}})
largest_number("-402,-1032!-569:-947;-633?-800!-1012;-402,-723?-8102!-3011") should return -402.
