Elegant 3 Line Solution (C++)


  • 1

    Why do it iteratively when it can be written in 3 lines...

    ListNode* removeElements(ListNode* head, int val) {
        if (!head) return head;
        head->next = removeElements(head->next, val);
        return (head->val == val)? head->next : head;
    }
