what is leet speak
Leetspeak (or leet) is an alternate representation of text that replaces letters with numbers or character combinations. For example, leet spellings of the word leet include 1337 and l33t. Note. Decoding is not always a bijective mapping! For example (if a -> 4 and 4 -> 4): encoded text 44 could be decoded into a4, 4a, 44 or aa.
