In John's car the GPS records every s seconds the distance travelled from an origin (distances are measured in an arbitrary but consistent unit). For example, below is part of a record with s = 15:
x = [0.0, 0.19, 0.5, 0.75, 1.0, 1.25, 1.5, 1.75, 2.0, 2.25]
The sections are:
0.0-0.19, 0.19-0.5, 0.5-0.75, 0.75-1.0, 1.0-1.25, 1.25-1.50, 1.5-1.75, 1.75-2.0, 2.0-2.25
We can calculate John's average speed per hour on every section and we get:
[45.6, 74.4, 60.0, 60.0, 60.0, 60.0, 60.0, 60.0, 60.0]
Given s and x the task is to return as an integer the floor of the maximum average speed per hour obtained on the sections of x. If x length is less than or equal to 1 return 0: the car didn't move.
Example:
with the above data your function gps(x, s) should return 74
