How to Memorize "edgecase"

1. visualize
   

   - Imagine a graph with input values on the x-axis and system behavior on the y-axis. Edge cases correspond to the extreme points on the graph where the behavior changes.

2. associate
   

   - Associate the term 'edge case' with the concept of 'extreme conditions'. Remember that edge cases reveal unusual or unexpected behavior.

3. mnemonics
   

   - Use the mnemonic 'ECC' for 'Edge Case Corner' to remember that edge cases occur at the extreme corners of the input domain.
