Kata Task
You are given a list of cogs in a gear train
Each element represents the number of teeth of that cog
e.g. [100, 50, 25] means
- 1st cog has 100 teeth
- 2nd cog has 50 teeth
- 3rd cog has 25 teeth
If the nth cog rotates clockwise at 1 RPM what is the RPM of the cogs at each end of the gear train?
Notes
- no two cogs share the same shaft
- return an array whose two elements are RPM of the first and last cogs respectively
- use negative numbers for anti-clockwise rotation
- for convenience
nis zero-based - For C and NASM coders, the returned array will be
free'd.
