Unsafe类中有很多以BASE_OFFSET结尾的常量,比如ARRAY_INT_BASE_OFFSET,ARRAY_BYTE_BASE_OFFSET等,这些常量值是通过arrayBaseOffset方法得到的。arrayBaseOffset方法是一个本地方法,可以获取数组第一个元素的偏移地址。Unsafe类中还有很多以INDEX_SCALE结尾的常量,比如 ARRAY_INT_INDEX_SCALE , ARRAY_BYTE_INDEX_SCALE等...

给定一个链表,两两交换其中相邻的节点,并返回交换后的链表。 示例: 给定1->2->3->4, 你应该返回 2->1->4->3. 说明: 你的算法只能使用常数的额外空间。 你不能只是单纯的改变节点内部的值,而是需要实际的进行节点交换。 classSolution{public:ListNode*swapPairs(ListNode*head){if(head==NULL)returnNULL...
