title: Can You Use Arithmetic Operators to Flip Between 0 and 1
body: <p>Is there a way without using logic and bitwise operators, just arithmetic operators, to flip between integers with the value 0 and 1?</p>
  <p>ie.
  <code>variable ?= variable</code> will make the variable 1 if it 0 or 0 if it is 1.</p>
