shell script
数值运算： $((计算式))， total = $((${var1}*${var2}))
/path/to/scriptname opt1 opt2 opt3 opt4
$0 $1 $2 $3 $4
$# ：代表后接的参数“个数”，以上表为例这里显示为“ 4 ”；
$@ ：代表“ "$1" "$2" "$3" "$4" ”之意，每个变量是独立的（用双引号括起来）；
$* ：代表“ "$1c$2c$3c$4" ”，其中 c 为分隔字符，默 认为空白键， 所以本例中代表“ "$1 $2 $3 $4" ”之意。
关于某个文件名的“文件类 型”判断
test -e filename 该“文件名”是否存在
-f 该“文件名”是否存在且为文件
-d 该“文件名”是否存在且为目录
-L 该“文件名”是否存在且为一个链接文件
关于文件的权限侦测
test -r filename 该“文件名”是否存在且具有“可读”的权限
-w 该“文件名”是否存在且具有“可写”的权限
-x 该“文件名”是否存在且具有“可执行”的权限
-u 该“文件名”是否存在且具有“SUID”的属性
-g 该“文件名”是否存在且具有“SGID”的属性
-k 该“文件名”是否存在且具有“Sticky bit”的属性
-s 该“文件名”是否存在且为“非空白文件”
两个文件之间的比较
test file1 -nt file2 判断 file1 是否比 file2 新
-ot 判断 file1 是否比 file2 旧
-ef 判断 file1 与 file2 是否为同一文件，可用在判断 hard link 的判定上
关于两个整数之间的判定
test n1 -eq n2 两数值相等 （equal）
-ne 两数值不等 （not equal）
-gt n1 大于 n2 （greater than）
-lt n1 小于 n2 （less than）
-ge n1 大于等于 n2 （greater than or equal）
-le n1 小于等于 n2 （less than or equal）
判定字串的数据
test -z string 判定字串是否为 0? 若 string 为空字串，则为 true
test -n string 判定字串是否为非0? 若 string 为空字串，则为 false, -n 亦可省略
test str1 == str2 判定 str1 是否等于 str2 ，若相等，则回传 true
test str1 != str2 判定 str1 是否不等于 str2 ，若相等，则回传 false
多重条件判定
test -r filename -a -x filename 两条件同时成立, 才回传 true
test -r filename -o -x filename 两条件任何一个成立，就可回传 true
test ! -x file 当 file 不具有 x 时，回传 true
判断符号 [ ]，功能类似test
在中括号内的每个元件都需要有空白键来分隔；
在中括号内的变量，最好都以双引号括号起来；
在中括号内的常数，最好都以单或双引号括号起来。
[ -z "${HOME}" ] 判断${HOME} 这个变量是否为空
条件判断式
if [ 条件判断式一 ]; then
当条件判断式一成立时，可以进行的指令工作内容；
elif [ 条件判断式二 ]; then
当条件判断式二成立时，可以进行的指令工作内容；
else
当条件判断式一与二均不成立时，可以进行的指令工作内容；
fi
case ..... esac 判断
case $变量名称 in
"第一个变量内容"）
程序段
;;
"第二个变量内容"）
程序段
;;
*）
不包含第一个变量内容与第二个变量内容的其他程序执行段
exit 1
;;
esac
while do done, until do done （不定循环）
当 condition 条件成立时，就进行循环，直 到 condition 的条件不成立才停止
while [ condition ]
do <==do 是循环的开始！
程序段落
done <==done 是循环的结束
当 condition 条件成立时，就终止循环， 否则就持续进行循环的程序段
until [ condition ]
do
程序段落
done
for...do...done （固定循环）
for var in con1 con2 con3 ...

/path/to/scriptname opt1 opt2 opt3 opt4
$0 $1 $2 $3 $4
$# ：代表后接的参数“个数”，以上表为例这里显示为“ 4 ”；

$* ：代表“ "$1c$2c$3c$4" ”，其中 c 为分隔字符，默 认为空白键， 所以本例中代表“ "$1 $2 $3 $4" ”之意。

Git
版本回退：
git log: 查看提交历史
git log --graph: 查看分支合并图
git reflog: 查看命令历史
git reset --hard commit_id: 回退到了某个版本
git reset --hard HEAD^: 回退到上一个版本
git reset --hard HEAD~10: 回退到之前第十个版本
撤销修改：
git checkout -- file: 可以丢弃工作区的修改(或删除操作), 让file这个文件回到最近一次git commit或git add时的状态
git reset HEAD file: 可以把暂存区的修改撤销掉，重新放回工作区
分支管理：
git merge --no-ff -m <commit-info> <branch-name>: 强制禁用Fast forward模式，Git就会在merge时生成一个新的commit，从分支历史上就可以看出分支信息
git stash: 把当前工作现场“储存”起来
git stash apply: 恢复储存的内容，但是恢复后，stash内容并不删除
git stash drop: 删除stash的内容
git stash pop: 恢复的同时把stash内容也删了
git stash apply stash@{0}: 如果有多次stash的话，选择恢复某个stash内容
配置别名：
git config --global alias.lg "log --color --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit"

Sliding Window Second Maximum
Given an array nums, there is a sliding window of size k which is moving from the very left of the array to the very right. You can only see the k numbers in the window. Each time the sliding window moves right by one position.
For example:
Given nums =
Then, return the second max sliding window [1, -1, -1, 3, 5, 6] .
/* time: amortized O(n), space:O(n) */
import java.util.*;
public class Solution {
