One website provides the following formula for the energy requirements on a typical road bike: E=C69.783.509+0.258C+H2+10.32M0.01s+0.103a{“version”:”1.1″,”math”:”E=C69.783.509+0.258C+H2+10.32M0.01s+0.103a”} where: E = energy expended at the pedal in calories/min C = speed of cyclist in meters/sec H = headwind in meters/sec M = total mass of a cyclist and bicycle in kg s = slope or grade in percentage points a = acceleration of the bicycle in meters/sec2 What would be the energy required for a cyclist with no headwind, on a 1% road grade (s = 1), at a constant speed (no acceleration), on a road bike weighing 85 kg including the rider, and going 7.15 meters/sec?  In case you are wondering, the 7.15 meters/sec speed is about 16 miles per hour in English units. But you don’t need to know that; just fill in the given metric units.

Consider the following recursive function: def r(xs: list[int]) -> list[int]:    match xs:        case []:            return []        case [x]:            return [x]        case [first, second, *rest]:            return [first] + r(rest) + [second] What list will r([1, 2, 3, 4]) return?
