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 m...

Given two sorted integer arrays A and B, merge B into A as one sorted array.
Note:
You may assume that A has enough space (size that is greater or equal to m +
n) to hold additional elements from B...

1. Sed简介sed 是一种在线编辑器,它一次处理一行内容。处理时,把当前处理的行存储在临时缓冲区中,称为“模式空间”(pattern space),接着用sed命令处理缓冲区中的内容,处理完成后,把缓冲区的内容送往屏幕。接着处理下一行,这样不断重复,直到文件末尾。文件内容并没有 改变,除非你使用...

在引进Compacting GC后,ART运行时优化了堆内存分配过程。最显著特点是为每个ART运行时线程增加局部分配缓冲区(Thead Local Allocation Buffer)和在OOM前进行一次同构空间压缩(Homogeneous Space Compact)。前者可提高堆内存分配效率,后者可解决内存碎片问题。本文就对ART运行时引进Compacting GC后的堆内存分配过程进行分析。...
