Consider the attached C source file (sltcll.c) containing part of the implementation of a dynamic (can grow and shrink during run-time) linked list. Compose your answers to following questions (based on sltcll.c) and submit as a single PDF document. a) Explain the working (logic) of the insert (struct node* insert(int d, struct node* h)) function in your words. b) Explain the working (logic) of the display (insertdisplayLL(struct node* h)) function in your words.
