How far apart

Problem

Write a function that takes two numbers and returns how far apart they are on the number line. From 3 to 10 there are 7, and from 10 to 3 there are 7 as well: the order you get them in doesn't matter and the answer is never negative.

If both numbers are the same, they are 0 apart.

Examples

• 3, 10 → 7

• 10, 3 → 7

• -4, 6 → 10

Besides these, the challenge has hidden tests that are revealed when you submit your solution.

You start with this

def distance(a, b):
    pass

function distance(a, b) {
}
