This is the next step up from Problem 42809.
Given a vector, v, of integers (negative or positive), return a vector, w, by sorting v in ascending order, such that primary sorting is done by the first digit (representing the largest value), secondary sorting by the second digit (next largest value), and so on.
v = [14 3 268 -14 210 1 80];
w = [1 -14 14 210 268 3 80];
As shown above, in cases of multiple integers starting with the same digits, such as 1 and 14, shorter integers take precedence.
Negative integers take precedence over positive integers.
