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 ## Input Will contain a single string to be translated ## Output Return a leet translated piece of string [samples]

**Definitions** Let $ S $ be a string over the alphabet $ \Sigma = \{a, b, c, \dots, z, A, B, \dots, Z, \text{digits}, \text{punctuation}, \dots\} $. Let $ \sigma: \{a, b, e, i, l, o, s, t, z\} \to \{4, 8, 3, 1, 1, 0, 5, 7, 2\} $ be the substitution mapping: $$ \sigma(a) = 4,\ \sigma(b) = 8,\ \sigma(e) = 3,\ \sigma(i) = 1,\ \sigma(l) = 1,\ \sigma(o) = 0,\ \sigma(s) = 5,\ \sigma(t) = 7,\ \sigma(z) = 2 $$ **Constraints** - $ S $ contains only printable ASCII characters. - Only lowercase letters $ \{a, b, e, i, l, o, s, t, z\} $ are subject to substitution; all other characters remain unchanged. - Uppercase variants of these letters are **not** substituted. **Objective** Compute the transformed string $ S' $ such that for each character $ c \in S $: $$ S'[i] = \begin{cases} \sigma(c) & \text{if } c \in \{a, b, e, i, l, o, s, t, z\} \\ c & \text{otherwise} \end{cases} $$
