The list is guaranteed to be sorted in ascending order. 和之前那道Remove Duplicates from Sorted List不同的地方是这里要删掉所有的重复项,由于链表开头可能会有重复项,被删掉的话头指针会改变,而最终却还需要返回链表的头指针。所以需要定义一个新的节点,然后链上原链表,然后定义一个前驱指针和一个现指针,每...
seen=set()forcharinstring:ifcharnotinseen: seen.add(char) result.append(char)return''.join(result) The time complexity of the algorithm is O(N) where N is the number of characters in the input string, because set supports O(1) insert and find. This is an optimal solution to one of...
