题目描述: 解题思路: 给定两个链表(代表两个非负数),数字的各位以倒序存储,将两个代表数字的链表想加获得一个新的链表(代表两数之和). 如(2->4->3)(342) + (5->6->4)(465) = (7->0->8)(807) 设两个进行加法运算的链表分别为l1,l2, 结果链表为resultList,以l1[i] 表示链表l1的第i个节点的值,l2[i] 表示链表l2的第i个节点的值,carry[i]表示l[i]位相加产生的进位符. 则有以下结论: 当链表l…

题目: There are two sorted arrays A and B of size m and n respectively. Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)). 解题思路: 这道题,很容易想到的是先排序再直接定位中间那个数即可,m+n为偶数的话,应为中间两数之和除2,但时间复杂度不符合题目要求,还一种方法就是利用归并思想,因…
