SECTION III - ANALYSIS PROGRAM SEGMENTS ---------------------------------------
1) Here is the structure declaration of a doubly linked list
struct dlink { int nodeid; struct dlink *next; struct dlink *prev; } dlink_t;
A pointer of the head of the linked list is maintained as a global variable, whose definition is dlink_t *head;
The funtion remove_element(dlink_t *rp), needs to remove the node pointed to the rp and adjust the head.
The first node's prev and the last node's next are NULL.
remove_element(dlink_t *rp) { rp->prev->next = rp->next; rp->next->prev = rp->prev; if( head == rp) head = rp->next;

Six knights - P,Q,R,S,T and U - assemble for a long journey in two travelling parties. For security, each travelling party consists of at least two knights. The two parties travel by separate routes, northern and southern. After one month, the routes of the northern and southern groups converge for a brief time and at that point the knights can, if they wish, rearrange their travelling parties before continuing, again in two parties along separate northern and southern routes. Throughout the entire trip, the composition of travelling parties must be in accord with the following conditions
P and R are deadly enemies and, although they may meet briefly, can never travel together. p must travel in the same party with s Q cann't travel by the southern route U cann't change routes

SECTION III - ANALYSIS PROGRAM SEGMENTS ---------------------------------------
1) Here is the structure declaration of a doubly linked list
struct dlink { int nodeid; struct dlink *next; struct dlink *prev; } dlink_t;
A pointer of the head of the linked list is maintained as a global variable, whose definition is dlink_t *head;
The funtion remove_element(dlink_t *rp), needs to remove the node pointed to the rp and adjust the head.
The first node's prev and the last node's next are NULL.
remove_element(dlink_t *rp) { rp->prev->next = rp->next; rp->next->prev = rp->prev; if( head == rp) head = rp->next;
Which of the following statement is true about the function remove_element
A) It work when head is the same as rp B) It does not work when rp is the last element on the list c) It sets the head of the list correctly D) It works in all cases

If it is found a pointer to that location is returned else NULL is returned. This function works a) Always b) Always, but fails when the first byte contais the character c c) works when c is a non NULL character only d) Works only when the character c is found in the string answer: a

Six knights - P,Q,R,S,T and U - assemble for a long journey in two travelling parties. For security, each travelling party consists of at least two knights. The two parties travel by separate routes, northern and southern. After one month, the routes of the northern and southern groups converge for a brief time and at that point the knights can, if they wish, rearrange their travelling parties before continuing, again in two parties along separate northern and southern routes. Throughout the entire trip, the composition of travelling parties must be in accord with the following conditions
P and R are deadly enemies and, although they may meet briefly, can never travel together. p must travel in the same party with s Q cann't travel by the southern route U cann't change routes
16) If one of the two parties of knights consists of P and U and two other knights and travels by the southern route, the other members of this party besides P and U must be a) Q and S b) Q and T c) R and S d) R and T e) S and T
answer: e
17) If each of the two parties of knights consists of exactly three members, which of the following is not a possible travelling party and route? a) P,S,U by the northern route b) P,S,T by the northern route c) P,S,T by the southern route d) P,S,U by the southern route e) Q,R,T by the southern route
ans: b
18) If one of the two parties of knights consists of U and two other knights and travels by the northern route, the other memnbers of this party besides U must be a) P and S b) P and T c) Q and R d) Q and T e) R and T
answer: c
19) If each of the two parties of knights consists of exactly three members of different parties, and R travels by the northern route, then T must travel by the a) southern route with P and S b) southern route with Q and R c) southern route with R and U d) northern route with Q and R e) northern route with R and U
answer: a
20) If, when the two parties of knights encounter one another after a month, exactly one knight changes from one travelling party to the other travelling party, that knight must be a) P b) Q c) R d) S e) T
answer: e
