Leet, (also known as 1337 sp34k or Elite Speak), was a prominent use of letter swapping during early internet culture.

Set types of letters would be able to be substituted for different numbers which would have similarities to the letters they were replacing. For this basic translator, only these conversions are needed:

a = 4 b = 8 e = 3 i = 1 l = 1 o = 0 s = 5 t = 7 z = 2

Will contain a single string to be translated

Return a leet translated piece of string

this is a test input
