Go语言Slice操作.

1、基本用法: 
 a = append(a, b...)
 例如:list = appened(list,[]int{1,2,3,4}...)
 可以用来合并两个列表. 不用这样了 :list := make([]int,len(list1)+len(list2)) 然后再copy(list,list1) copy(list[len(list1):],list2)
2、Copy:
 b = make([]T, len(a)) copy(b, a)
或者:
 b = append([]T(nil), a...)
3、Cut:
 a = append(a[:i], a[j:]...)
4、Delete:
 a = append(a[:i], a[i+1:]...)
 或者: a = a[:i+copy(a[i:], a[i+1:])]
 例如:a[len(a)-1], a = nil, append(a[:i], a[i+1:]...)
5、Delete without preserving order: 
 a[i], a = a[len(a)-1], a[:len(a)-1]
 例如: a[i], a[len(a)-1], a = a[len(a)-1], nil, a[:len(a)-1]
6、Expand: 
 a = append(a[:i], append(make([]T, j), a[i:]...)...)
7、Extend: 
 a = append(a, make([]T, j)...)
8、Insert:
 a = append(a[:i], append([]T{x}, a[i:]...)...)
 例如: s = append(s, 0) copy(s[i+1:], s[i:]) s[i] = x
9、InsertVector:
 a = append(a[:i], append(b, a[i:]...)...)
10、Pop
 x, a = a[len(a)-1], a[:len(a)-1]
11、Push:
 a = append(a, x)
12、Shift 
 x, a := a[0], a[1:]
13、Unshift
 a = append([]T{x}, a...)
14、Reversing: 
 for i := len(a)/2-1; i >= 0; i-- { 
 opp := len(a)-1-i a[i], a[opp] = a[opp], a[i]
 }
