CSc 120: List to String (Recursive) Expected Behavior Write a ecursive function list2string(arglist), where arglist is a list of strings, that returns the string resulting from concatenating the elements of arglist. Programming Requirements Solve this problem using recursion. You are allowed to use only the following programming constructs .if statements; e return statements; . assignment; recursive function calls (but not to helper functions) . comparison operations (-,-, etc.); list indexing and slicing; list and string concatenation. Solutions that go outside these constructs, e.g., by using for/while loops or list comprehensions, will not get credit Examples 1. list2string(I'aa'bb', 'c', 'dd']) return value: aabbccdd 2. list2string(l'aa', 'bb',", cc',", 'dd'1) return value: 'aabbccdd' 3. list2string(l 'aa') return value 'aa 4. list2string(ti) return value: 5. 1ist2string(t"'1 return value
