[問題] 100台聯大系統堆疊問題
5.What is the top element of Stack S after execution of the pseudocode
program on the below?
Stack(S);//create a stack S
Queue(Q);//create a queue Q
Push(S,1);Push(S,2);
Push(S,3);Push(S,4);
Enqueue(Q,5);Enqueue(Q,6);
for(i=1 to 4){
x=Pop(S);
Enqueue(Q,x);
}
for(i=1 to 6){
x=Dequeue(Q);
Push(S,x);
}
a.4 b.3 c.2 d.1 e.None of the above
我認為答案的關鍵在top element of Stack
另一題也是台聯100
25.A stack is initially empty, then the following commands are performed:
push 5
push 7
pop
push 10
push 5
pop
Which of the following is correct stack after those commands(assume the top
of the stack is on the left)?
我認為答案的關鍵在也top element of Stack
所以能否請版上高手講解一下何謂堆疊頂端?如何去判別?謝謝大家!!
ps:A4的同志加油 實力才是唯一的靠山!!
