Remove Linked List Elements by Value

Given the head of a linked list and an integer `val`, remove all the nodes of the linked list that have `Node.val == val`, and return the new head. ### Constraints - The number of nodes in the list is in the range `[0, 5000]`. - `1 <= Node.val <= 50` - `0 <= val <= 50` ### Input Format First line contains the target integer `val`. Second line contains space-separated integers of the list (or empty). ### Output Format Print the space-separated integers of the modified list (or empty line).
