Using either compactor, the list comprehension is the dominating term here, with time =O(n*m), space = O(m+n), as it compares all possible combinations of the two lists with no early outs. This does not take advantage of the ordered structure of the lists given in the prompt: you c...
如果链表A长度大于链表B的长度,此时链表A就需要先向前移动两者之间长度差值个节点,然后才能和B开始依次遍历比较,反之B也是如此。 publicListNodegetIntersectionNode2(ListNode headA, ListNode headB){intlen1 = findLength(headA);intlen2 = findLength(headB);intdiff = (len1 >= len2) ? (len1 - len2)...

160. Intersection of Two Linked Lists, 相加链表 题意: 思路: 解题的关键是:创建出两个复制品,然后把它们连接起来; 解法1
LeetCode之Intersection of two linked list不同方法 AC完看答案发现答案超简单,而自己的方法有点过于复杂了,题目原意是找出两个链表第一个公共节点,如果没有则返回NULL。 看到题目后,我竟然想到可能存在交叉结构,结果通过反转一个链表来求出是否存在公共节点,但是却没法求出第一个公共节点,因此重新看回题目,发现...
