# Let S be the set of all strings in a’s and b’s and let L : S → Z be the length function:For all strings s ∈ S , L ( s ) = the number of characters in s. Let T : Z → { 0 ,   1 ,   2 } be the mod 3 function:For every integer n, T ( n ) = n   m o d   3 .a. ( T ∘ L ) ( a b a a ) = ? b. ( T ∘ L ) ( b a a a b ) = ? c. ( T ∘ L ) ( a a a ) = ?
