1. Write a structurally recursive function (prefix-of? 1st1 1st2) that takes two arguments, both flat lists. Either can be the empty list. prefix-of? returns true if 1st2 starts with the items in 1st1 in the same order, and false otherwise. For example: > (prefix-of? '(cs1510 cs1800) '(cs1510 cs1800 cs1520 cs1410)) #t > (prefix-of? '(cs1510 cs1800) '(cs1510 cs1520 cs180e)) #f The empty list is a prefix of every other list.

1. Write a structurally recursive function (prefix-of? 1st1 lst2) that takes two
arguments, both flat lists. Either can be the empty list. prefix-of? returns true if 1st2
starts with the items in 1st1 in the same order, and false otherwise. For example:
> (prefix-of? '(cs1510 cs1800) '(cs1510 cs1800 cs1520 cs1410))
#t
> (prefix-of? '(cs1510 cs1800) '(cs1510 cs1520 cs1800))
#f
The empty list is a prefix of every other list.
