You can implement the queue using circular arrays. But circular array changes the FIFO queue to a LIFO queue, I think. After the queue is full, i.e., there are 10 elements in the queue, the 11th element will be put at the first slot, c_array[0], other than c_array[9]. Jun 9...

注意循环数组进队列出队列的front 和rear都会变,所以会存在可能头尾都在数组中间一段,而前后是空的,由于是循环队列,我们在增加元素时,如果此时 rear = array.length - 1 ,rear 需要更新为 0;同理,在元素出队时,如果 front = array.length - 1, front 需要更新为 0. 对此,我们可以通过对数组容量取模来更新...

Implement Queue using Stacks 用栈来实现队列。 我记得在程序员面试金典上遇到过一样的题目,感觉是一道很经典的题目。需要面试者对队列和栈都非常熟悉才行。 Intuition: 队列是FIFO,栈是LIFO,所以我们可以用2个栈来实现一个队列。定义将一个栈装入另一个栈的操作为颠倒。我们可以通过颠倒, 将LIFO变为FIFO,而且只...
