in c++ language

Write a program that will read in two numbers in as strings. Your program should store the digits in the number as a sort linked list. Your program should then merge the two linked list together in sorted order into a new linked list without changing the original two linked list. Your merge algorithm needs to run in O(n+m) time with n and m being the length of the two linked lists. You merge algorithm must be recursive.
