What do you call "pre" here ? I see this is a reverse take on the accumulator in reduce.

why is this best practice if the sum 5050 is hard coded ? isn't a more general solution wherein the sum for the first 100 positive integers 0 included is calculated first the way to do it ?

the manager has an increment waiting for you for delivering such understandable code .

always tend to get stuck on katas by g964 so much so that everytime i see their question , I go - 'argh, here we go again' . great exercise for the gray matter :D
