Median of Two Sorted ArraysThere are two sorted arrays nums1 and nums2 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)).Exam

Add Two NumbersYou are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two number

[Easy]Two SumGiven an array of integers, return indices of the two numbers such that they add up to a specific target.You may assume that each input would have exactly one solution, and you may not use

描述 现在，有一行括号序列，请你检查这行括号是否配对。 输入第一行输入一个数N（0 输出每组输入数据的输出占一行，如果该字符串中所含的括号是配对的，则输出Yes,如果不配对则输出No 样例输入 3 [(]) (]) ([[]()]) 样例输出 No No Yes 解法一： 常规思路，对单个字符进行比较处理，不提供源代码 解法二：
