Use the $FIFODEQ macro to remove an element from a FIFO queue. The caller gives the address of a queue head, a queue tail, and the offset of a next and previous word for the work element and the address of the

一、Queue 队列通常但不一定以 FIFO(先进先出)的方式对元素进行排序。 例外情况包括:优先级队列,根据提供的比较器对元素进行排序,或者元素的自然排序;以及LIFO队列(或堆栈),对LIFO进行排序(后进先出)。 无论使用哪种排序,队列的head 都是元素,可以通过调用remove()或poll()来删除。在FIFO队列中,所有新元素都将插...
Queue中常用的element/peek,remove/poll,add/offer有什么不同 虽然ArrayList底层是数组,但是优化之后的增删操作依然不慢,这就使得LindedList的很少出现在我们视野当中。但是在涉及到Stack和Queue时候(主要是刷题时),LinkedList的还是很常见的,由于底层是双向链表,又实现了Deque接口,经常被繁多的方法搞得头晕,主要方法如...
