Korean cellco KTF demonstrated earlier this year the ability to roam between GSM and CDMA using such cards.However,only the card containing the user’s service data can roam-not the CDMA handset or the user’s number (except via call forwarding).

2. Programming (Mandatory)

Linked list

a. Implement a linked list for integers,which supports the insertafter (insert a node after a specified node) and removeafter (remove the node after a specified node) methods;

b. Implement a method to sort the linked list to descending order.

3. Debugging (Mandatory)

a. For each of the following recursive methods,enter Y in the answer box if themethod terminaters (assume i=

5), Otherwise enter N.

static int f(int i){

return f(i-

1)*f(i-

1);

}

Ansewr:

static int f(int i){

if(i==0){return 1;}

else {return f(i-

1)*f(i-

1);}

}

Ansewr:

static int f(int i){

if(i==0){return 1;}

else {return f(i-

1)*f(i-

2);}

}

Ansewr:

b. There are two errors in the following JAVA program:

static void g(int i){

if(i==

1){return;}

if(i%2==0){g(i/

2);return;}

　設“1”的坐標為（0，0） “7”的坐標為（－1，－

1) 編寫一個小程序，使程序做到輸入坐標（X,Y）之后顯示出相應的數字。

3、#include

　//example input and output

　//in 1 2 3 out 1 3 1

　//in 123456789 2 100 out 123456789 100 21

　long mex(long a,long b,long c)

　{ long d;

if(b==0) return 0;

if(b==

1) return a%c;

d=mex(a,b/2,c)； d*=d;這里忘了;d*=mex(a,b%2,c);d%=c;

return d;

　}

　int main(void)

　{ long x,y,z;

while(1)

{ if(scanf(%d %d %d,&x,&y,&z)>

3) return 0;

if(x<0) { printf("too small ");continue;}

if(y<0) { printf("too small ");continue;}

if(z<

1) { printf("too small ");continue;}

if(y>z) { printf("too big ");continue;}

if(z>10000000

10) {printf("too big ");continue}

printf(%d %d %d,x,z,mex(x,y,z);

　}}

　根據這個程序，當已知一個輸入，算出輸出，如：輸入 1 3 1 則輸出 1 2 3 輸入 123456789 100 21 輸出 123456789 2 100
