Write a Common Lisp function named clean which takes two parameters: aFunc and aList. aFunc will be a function and aList a list. aFunc is expected to be a function which takes a single parameter and returns a boolean value. clean will return a list which contains all values in aList which, when passed to aFunc, return true. if aList contains sublists, clean should create a new sublist with only the values which return true when passed to aFunc

;aFunc returns true if given value is a number (clean aFunc '(2 3 #\F 4 5 "Hello!") ) ;(2 3 4 5) (clean aFunc '(2 '(3 4 "World" 5 6 #\T 7) #\F 8 9 "Hello!")) ;(2 (3 4 5 6 7) 8 9)
