I need a code in C++. Please help me, thank you.
Problem 2. Write the following functions: a): merging two ordered singly linked lists of integers into one ordered list. b): concatenating two lists p1 and p2. c): checking whether two singly linked lists have the same contents. Suggestion: You can choose 1 between 2 ways 1) Write 3 functions: NumberLinkedList merge (NumberLinkedList p1, NumberLinkedList p2) NumberLinkedlist concatenate2Lists (NumberLinkedList p1, NumberLinkedlist p2) bool equal (NumberLinkedList p1, NumberLinkedList p2) 2) Write operations for NumberLinkedList class void merge (NumberLinkedlist); void concatenate (NumberLinkedList); bool equal(NumberLinkedList);
