用两个队列实现栈 (二)
my_stack.append_tail('a');
my_stack.append_tail('b');
my_stack.append_tail('c');
my_stack.Show_Stack();
my_stack.delete_head();
my_stack.delete_head();
my_stack.Show_Stack();
my_stack.append_tail('d');
my_stack.append_tail('e');
my_stack.Show_Stack();
my_stack.delete_head();
my_stack.Show_Stack();
my_stack.append_tail('f');
my_stack.Show_Stack();
}
/**************************
运行结果：
this is Show_Stack!从栈顶到栈底显示数据
c b a
this is Show_Stack!从栈顶到栈底显示数据
a
this is Show_Stack!从栈顶到栈底显示数据
e d a
this is Show_Stack!从栈顶到栈底显示数据
d a
this is Show_Stack!从栈顶到栈底显示数据
f d a
