Remove all elements from a linked list of integers that have value val.
Example:
Input: 1->2->6->3->4->5->6, val = 6 Output: 1->2->3->4->5
如果第一个数字，就需要删除，那么需要重置head。所以自己构建1个myHead。
public ListNode RemoveElements(ListNode head, int val) { ListNode myHead = new ListNode(0); myHead.next = head; ListNode current = head; ListNode currentPrev = myHead; while (current != null) { if (current.val == val) { current = current.next; currentPrev.next = current; } else { currentPrev = current; current = current.next; } } return myHead.next; }
Remove all elements from a linked list of integers that have value val.
Example:
Input: 1->2->6->3->4->5->6, val = 6 Output: 1->2->3->4->5
