## Create distance vector

## Part A

## loop through all the runs
## loop through milliseconds per run
## calculate distance per time span button holding
## compare with record distance of run
## count up win possibilities
## multiply the win possiblities of all runs


## PartB

## Transform distance and time to one pasted integer
## and feed to the loop described in outline for PartA



## Result Loop

runs = length(time_partB)
wins = zeros(Int, length(time_partB))
for i in 1:runs

   milliseconds = time_partB[i]

   for speed in 0:milliseconds

        dist_achieved = (milliseconds - speed) * speed # Δpushbutton = speed

        if dist_achieved > distance_partB[i]
            wins[i] += 1
