Please solve problem b.
Describe and Justify the proofs
(b-dfa) Let us define an operation truncate, which removes the rightmost symbol from any string. For example, truncate (aaaba) is aaab. The operation can be extended to languages by
truncate (L) = {truncate (w) : w L} .
Show how, given a dfa for any regular language L, one can construct a dfa for truncate (L). From this, prove that if L is a regular language not containing , then truncate (L) is also regular.
