类似题目:LeetCode 67 - Add Binary | 二进制求和 (Rust) 时间复杂度:O(|l1| + |l2|) 需要遍历 l1 中的全部 O(|l1|) 个结点 需要遍历 l2 中的全部 O(|l2|) 个结点 空间复杂度:O(1) 需要为结果链表中的全部 O(max(|l1|, |l2|)) 个结点分配空间 (理论上可以复用已有的结点,这样就只需要定义常数个
445. Add Two Numbers II 这个题和Add Two Numbers相似,但是这个题是把最高位放在了链表的前面,但数字的相加必须从最低位开始。 可以选择用栈来存储数字,也可以使用链表反转。 使用链表反转,先将l1、l2反转,然后时候用和Add Two Numbers一样的方法做计算,然后再反转这个生成的记过就好了。 classSolution {public...
