+版本一（在原链表上直接删除）：
+
+```typescript
+/**

+ * class ListNode {
+ *     val: number
+ *     next: ListNode | null
+ *     constructor(val?: number, next?: ListNode | null) {

+    while (head !== null && head.val === val) {
+        head = head.next;

+        }
+        cur = cur.next;
+    }
+    return head;

+```
+
+版本二（虚拟头节点）：
+
+```typescript
+function removeElements(head: ListNode | null, val: number): ListNode | null {
+    head = new ListNode(0, head);
+    let pre: ListNode = head, cur: ListNode = head.next;
+    // 删除非头部节点
+    while (cur) {
+        if (cur.val === val) {
+            pre.next = cur.next;
+        } else {
+            pre = pre.next;
+        }
+        cur = cur.next;
+    }
+    return head.next;
+};
+```
