Construct a recursive function to compute the nth term of the Jacobsthal-Lucas sequence, ensuring its efficiency in handling large numbers without triggering overflow. The function must incorporate input validation to confirm the input is a positive integer.
To augment the complexity, the function should also be capa... | codefeedback | [
