The first and last stop

Problem

A bus route arrives as a list with the names of its stops in order, and all you care about are the two ends.

Write a function that returns a new list with two names: the first stop and the last one, in that order. With ["Downtown", "Hospital", "Market", "Airport"] you return ["Downtown", "Airport"].

A route can have any number of stops, but it is never empty. If it has a single stop, that one is the first and the last at the same time: with ["Old Mill"] you return ["Old Mill", "Old Mill"].

Examples

• Four stops

  ["Downtown", "Hospital", "Market", "Airport"] → ["Downtown", "Airport"]

• Only two stops

  ["North Gate", "South Gate"] → ["North Gate", "South Gate"]

• Five stops

  ["Riverside", "Bell Tower", "Museum", "Garden", "Harbor"] → ["Riverside", "Harbor"]

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

You start with this

def ends(route):
    pass

function ends(route) {
}
