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```

```/**
* public class ListNode {
*     int val;
*     ListNode next;
*     ListNode() {}
*     ListNode(int val) { this.val = val; }
*     ListNode(int val, ListNode next) { this.val = val; this.next = next; }
* }
*/
class Solution {
public ListNode removeElements(ListNode head, int val) {
ListNode prev = new ListNode(-1);

while(curr != null){
if(curr.val == val){
prev.next = curr.next;
}else{
prev = prev.next;
}

curr = curr.next;
}

}
}```
