Given a linked list and a value x, partition it such that all nodes less than x come before nodes greater than or equal to x. You should preserve the original relative order of the nodes in each of the two partitions. Example: Input: head = 1->4->3-…

/* 这个题是medium的意思应该是用双指针的方法做,如果使用下边的新建链表的方法,就是easy的题目了 双指针会用到很多链表的相连操作 */ public ListNode partition(ListNode head, int x) { ListNode s = null; ListNode b = null; ListNode temp=null,res=null; while (head!=null) { int cur = head.val; if (head.val<x) { i…
