Let bin(n) denote the binary representation of n > 0, leading zeros omitted. For example, bin(0) = 0, bin(5) = 101, and bin(12) = 1100. (a) Show that the language {bin(n)#bin(n+1)} is not a context-free language
(b) Suppose we reverse the first numeral; that is, consider the language {bin(n)"#bin(n+1)}
Show that this language is context-free.

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
