--description--

Given a positive integer, return a string with all of the integers from 1 up to, and including, the given number, in numerical order.

For example, given 5, return "12345".

--hints--

sequence(5) should return "12345".

assert.equal(sequence(5), "12345");

sequence(10) should return "12345678910".

assert.equal(sequence(10), "12345678910");

sequence(1) should return "1".

assert.strictEqual(sequence(1), "1");

sequence(27) should return "123456789101112131415161718192021222324252627".

assert.equal(sequence(27), "123456789101112131415161718192021222324252627");
