Dangling Suffix Checker

Author: Levindo Gabriel Taschetto Neto

Basic Theory

The dangling suffix checking is a technique which might be used to test the unique decodability of a code.

Examples

Example 1

Code: A

Symbols	Code A
A	0
B	10
C	001

High-Level execution

["0", "10", "001"]
["0", "10", "001", "01"] # Because "0" is suffix of "001"
["0", "10", "001", "01", "1"] # Because "0" is suffix of "01", so the rest "1" ought be added in the list
["0", "10", "001", "01", "1", "0"] # Because "1" is suffix of "10", so the rest "0" ought be added in the list

Thus, during the execution, two elements with the same value were found. In this case, the code A is labeled as "not uniquely decodable"
