Questions 1-7 are based on the following program, #include using namespace std; class cList { public: cList(); ~cList(); cList(int n); int getNum(); cList *previous; cList *next; …

#include [removed]

using namespace std;

class cList {
public:
cList();
~cList();
cList(int n);
int getNum();

cList *previous;
cList *next;

private:
int num;
};

cList::cList() // Question c).

cList::~cList() { } // Question d).

cList::cList(int n) // Question e).

int cList::getNum() {
return num;
}

int function1(int m) {
return (m%3);
}

int main() {
cList *p1 = new cList(21);
cList *p2 = new cList(3);
cList *p3 = new cList(80);
cList *p4 = new cList(16);

p1→previous = p4;
p1→next = p2;

p2→previous = p1;
p2→next = p3;

p3→previous = p2;
p3→next = p4;

p4→next = p1;
p4→previous = p3;

cList *current = p3;

while (current→next != p3) {
cout << function1(current→getNum()) << “n”;
current = current→next;
}

while (current→previous != p2) {
cout << function1(current→getNum()) << “n”;
for (int i=0; i[removed]= 1.
c. Implement a function that returns the value of the nth number in this sequence.

9. Suppose there are seven players playing Halo3. They are CatchMeIfYouCan, Halo4, Fake1, SweetGirl, NaughtyBoy, GoldenFinger, and FireBall. Their scores are as indicated in the following Table 1,

Name Score
CatchMeIfYouCan 1500
Halo4 3500
Fake1 1000
SweetGirl 2200
NaughtyBoy 1960
GoldenFinger 12900
FireBall 5800

Table 1. Players and Scores

Now use BubbleSort algorithm to sort the players in the descending order of their scores. Write down/ draw the table of each intermediate step/ round and determine how many steps/ rounds BubbleSort uses totally. (15 points)
