A sorting algorithm where every other element is swapped with the previous element, then every 3rd element is swapped with the previous element, then every 4th element is swapped with the previous element, and ao on, until only the last element is swapped.

A retarder is a device used to augment or replace some of the functions of primary friction-based braking systems, usually on heavy vehicles. Retarders serve to slow vehicles, or maintain a steady speed while traveling down a hill, and help prevent the vehicle from "running away" by accelerating down the hill. They are not usually capable of bringing vehicles to a standstill, as their effectiveness diminishes as vehicle speed lowers. They are usually used as an additional "assistance" to slow vehicles, with the final braking done by a conventional friction braking system. As the friction brake will be used less, particularly at higher speeds, their service life is increased, and since in those vehicles the brakes are air-actuated helps to conserve air pressure too.
Friction-based braking systems are susceptible to "brake fade" when used extensively for continuous periods, which can be dangerous if braking performance drops below what is required to stop the vehicle – for instance if a truck or bus is descending a long decline. For this reason, such heavy vehicles are frequently fitted with a supplementary system that is not friction-based.
Retarders are not restricted to road motor vehicles, but may also be used in railway systems. The British prototype Advanced Passenger Train (APT) used hydraulic retarders to allow the high-speed train to stop in the same distance as standard lower speed trains, as a pure friction-based system was not viable.

Joey:what’s 4+4???
Friend:how do you not know what 4+4 is Joey your a retard!
Joey:what’s. Retard??
Friend:a retard is someone who is really dumb,stupid,and painful to hang out with
Joey:I’m offended

A group of two or more weebs is called a Retardation. they typically do not use deodorant and smell of death. avoid a Retardation at all costs.
