Number Needed to Treat Point

Problem

The number needed to treat is the reciprocal of the absolute risk difference: 1 / |risk_treated - risk_control|.

Given the two risks (not equal), return the number needed to treat.

Hint

Take the absolute difference so the direction of benefit does not matter.
