走访Linked List 时考虑进位 给出两个 非空 的链表用来表示两个非负的整数。其中,它们各自的位数是按照 逆序 的方式存储的,并且它们的每个节点只能存储 一位 数字。 如果,我们将这两个数相加起来,则会返回一个新的链表来表示它们的和。 您可以假设除了数字 0 之外,这两个数都不会以 0 开头。 示例: 输入:...

ConcurrentLinkedQueue是Queue的一个安全实现.Queue中元素按FIFO原则进行排序.采用CAS操作,来保证元素的一致性。 LinkedBlockingQueue是一个线程安全的阻塞队列,它实现了BlockingQueue接口,BlockingQueue接口继承自java.util.Queue接口,并在这个接口的基础上增加了take和put方法,这两个方法正是队列操作的阻塞版本。
assuming the hash function disperses elements properly among the buckets. Performance is likely to be just slightly below that ofHashSet, due to the added expense of maintaining the linked list, with one exception: Iteration over aLinkedHashSetrequires time proportional to thesizeof the set, rega...
