title: What is the difference between an edge case and a corner case?
body: <p>I've seen the two terms use interchangeably. Definitions found online seem to vary as well.</p>
  
  <p>From my understanding, a corner case is the extreme values of inputs. And edge cases are the extreme cases to handle when designing an algorithm. Is this correct?</p>
  
  <p>Is there a standard definition?</p>
