if first < end:
mid = (first+end)//2
merge(a, first, mid, temp) #前半部...

【题目】
Given a linked list, swap every two adjacent nodes and return its head.
For example,
Given 1->2->3->4, you should return the list as 2->1->4->3.
Your algorithm should use only constant space. You may not modify the values in the list, only nodes it...

题目:给定一个数组,以及一个 target 值,target 表示目标和,要求在数组中找到两个数,xi,xj,使得 xi + xj = target。返回值是找到的两个数的下标索引,升序排序。假定至少存在一对解。
分析:对于要处理数组的问题,我们的理想状态都是给定的数组是有序的就好了,在有序后,我们就可以首位各放一个标记。类似于二分查找。

Problem Description
For a decimal number x with n digits (AnAn-1An-2 ... A2A1), we define its weight as F(x) = An * 2n-1 + An-1 * 2n-2 + ... + A2 * 2 + A1 *
1. Now you are given two numbers A and...
