203. Remove Linked List Elements

Practice Remove Linked List Elements for free on NudgeCode: Easy, Linked List pattern. Write it in Python or JavaScript, run the tests in your browser, and ask for a hint when you are stuck.

Delete every node whose value equals val from a linked list and return the head of what remains. The head itself may need to be deleted, and the result may be empty.

Example

head = [1,2,6,3,4,5,6], val = 6  ->  [1,2,3,4,5]
head = [7,7,7,7], val = 7        ->  []

Constraints

• 0 <= length of the list <= 10^4
• 1 <= Node.val <= 50
• 0 <= val <= 50
