Define the rule nthElem(LST, ELEM, IND). This rule describes how the number IND ndexes ELEM in the list LST. This is very similar to list length except that your pase case is not an empty list, but that the index refers to the first element of the list. e.g.: nthElem([1, 2, 3], 2, 1). true ? nthElem([1, 2, 3], 2, -1). no nthElem([1, 2, 3], 2, A). A = 1 ? nthElem([1, 2, 3], A, 1). A = ??

Please use Prolog programming language

Define the rule nthElem(LST, ELEM, IND). This rule describes how the number IND indexes ELEM in the list LST. This is very similar to list length except that your base case is not an empty list, but that the index refers to the first element of the list. e.g.: nthElem([1, 2, 3], 2, 1). true ? nthElem([1, 2, 3], 2, -1). no nthElem([1, 2, 3], 2, A). A = 1? nthElem([1, 2, 3], A, 1). A= 2 ?
