 The best way to mitigate this is to check if an ID is "canonical" before using its decoded value to do a database lookup, for example; and this can be done by simply re-encoding the decoded number(s) and checking if the result matches the incoming ID:
 
 ```cs
-int[] numbers = sqids.Decode(input);
+var numbers = sqids.Decode(input);
 bool isCanonical = input == sqids.Encode(numbers); // If `input` is `OSc`, this evaluates to `true` (because that's the canonical encoding of `3168`), and if `input` is `2fs`, it evaluates to `false`.
 ```
