pop操作用于从栈顶弹出元素。在Python中,我们可以使用列表的pop方法来实现pop操作。下面是一个示例代码: AI检测代码解析 stack=[1,2,3]top_element=stack.pop()print(top_element)# Output: 3print(stack)# Output: [1, 2] 1. 2. 3. 4. 5. 6. 在上面的代码中,我们首先创建了一个包含元素1、2和3...
if__name__=="__main__":my_stack=Stack()# 添加元素my_stack.push(1)my_stack.push(2)my_stack.push(3)# 显示栈的当前状态print("当前栈状态:")my_stack.display()# 缓存顶端元素top_element=my_stack.peek()print(f"栈顶元素是:{top_element}")# 移除元素whilenotmy_stack.is_empty():popped...
