In order to rotate 90 degree:
- swap the matrix top-down
- swap the matrix according the trace line
So that we can get the matrix.
From the problem, we can know that a complexity can be decompose to some simple action.
Error:
N/A

编译安装 Hive如果需要直接安装 Hive,可以跳过编译步骤,从 Hive 的官网下载编译好的安装包,下载地址为http://hive.apache.org/downloads.html。Hive的环境配置需要MySQL的支持,所以首先需要安装MySQL,没有安装MySQL的先看上一篇:安装MySQL C.1 编译HiveC.1.1 下载 Hive 源代码包在 Hive
