--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--
largestNumber("1,2") should return 2.
assert.equal(largestNumber("1,2"), 2);
largestNumber("4;15:60,26?52!0") should return 60.
assert.equal(largestNumber("4;15:60,26?52!0"), 60);
largestNumber("-402,-1032!-569:-947;-633?-800!-1012;-402,-723?-8102!-3011") should return -402.
assert.equal(largestNumber("-402,-1032!-569:-947;-633?-800!-1012;-402,-723?-8102!-3011"), -402);
largestNumber("12;-50,99.9,49.1!-10.1?88?16") should return 99.9.
assert.equal(largestNumber("12;-50,99.9,49.1!-10.1?88?16"), 99.9);
