zhe.ink切片排序或搜索功能允许您以各种方式与切片进行交互和操作。Golang排序函数是核心的一部分。使用此功能无需安装，只需导入"sort"包即可。借助排序功能，您可以搜索任何重要的Golang排序函数列表如下：
Ints函数按升序对整数切片进行排序。
func Ints(intSlice []int)示例代码：
package main
import (
"fmt"
"sort"
)
func main() {
intSlice := []int{10, 5, 25, 351, 14, 9} // unsorted
fmt.Println("Slice of integer BEFORE sort:",intSlice)
sort.Ints(intSlice)
fmt.Println("Slice of integer AFTER sort:",intSlice)
}输出：
Slice of integer BEFORE sort: [10 5 25 351 14 9]
Slice of integer AFTER sort: [5 9 10 14 25 351]
Strings函数按字典升序对字符串切片进行排序。

fmt.Println("Slice of string BEFORE sort:",strSlice)
sort.Strings(strSlice)
fmt.Println("Slice of string AFTER sort:",strSlice)
fmt.Println("\n-----------------------------------\n")
strSlice = []string{"JAMAICA","Estonia","indonesia","hong Kong"} // unsorted
fmt.Println("Slice of string BEFORE sort:",strSlice)
sort.Strings(strSlice)
fmt.Println("Slice of string AFTER sort:",strSlice)
}输出：
Slice of string BEFORE sort: [Jamaica Estonia Indonesia Hong Kong]

fmt.Println("Slice BEFORE sort: ",fltSlice)
sort.Float64s(fltSlice)
fmt.Println("Slice AFTER sort: ",fltSlice)
}输出：
Slice BEFORE sort: [1.8787677878716e+07 565435.321 7888.545 8.7876778716e+06 987654.252]

x := 18
pos := sort.SearchInts(intSlice,x)
fmt.Printf("Found %d at index %d in %v\n", x, pos, intSlice)
// slice need to be sort in ascending order before to use SearchInts
sort.Ints(intSlice) // slice sorted
pos = sort.SearchInts(intSlice,x)
fmt.Printf("Found %d at index %d in %v\n", x, pos, intSlice)
x = 54
pos = sort.SearchInts(intSlice,x)
fmt.Printf("Found %d at index %d in %v\n", x, pos, intSlice)
x = 99
pos = sort.SearchInts(intSlice,x)
fmt.Printf("Found %d at index %d in %v\n", x, pos, intSlice)

intSlice := []int{55, 54, 53, 52, 51, 50, 48, 36, 15, 5} // sorted slice in descending
x := 36
pos := sort.SearchInts(intSlice,x)
fmt.Printf("Found %d at index %d in %v\n", x, pos, intSlice)
fmt.Println("\n######## Search works in descending order ########")
i := sort.Search(len(intSlice), func(i int) bool { return intSlice[i] <= x })
fmt.Printf("Found %d at index %d in %v\n", x, i, intSlice)
fmt.Println("\n\n######## SearchStrings not works in descending order ######## ")
// sorted slice in descending
strSlice := []string{"Washington","Texas","Ohio","Nevada","Montana","Indiana","Alaska"}
y := "Montana"
posstr := sort.SearchStrings(strSlice,y)
fmt.Printf("Found %s at index %d in %v\n", y, posstr, strSlice)
fmt.Println("\n######## Search works in descending order ########")
j := sort.Search(len(strSlice), func(j int) bool {return strSlice[j] <= y})
fmt.Printf("Found %s at index %d in %v\n", y, j, strSlice)
fmt.Println("\n######## Search works in ascending order ########")
fltSlice := []float64{10.10, 20.10, 30.15, 40.15, 58.95} // string slice in float64
z := 40.15
k := sort.Search(len(fltSlice), func(k int) bool {return fltSlice[k] >= z})
fmt.Printf("Found %f at index %d in %v\n", z, k, fltSlice)

// the Price field.
type ByPrice []Mobile
func (a ByPrice) Len() int { return len(a) }
func (a ByPrice) Swap(i, j int) { a[i], a[j] = a[j], a[i] }
func (a ByPrice) Less(i, j int) bool { return a[i].Price < a[j].Price }
// ByBrand implements sort.Interface for []Mobile based on
// the Brand field.
type ByBrand []Mobile
func (a ByBrand) Len() int { return len(a) }
func (a ByBrand) Swap(i, j int) { a[i], a[j] = a[j], a[i] }
func (a ByBrand) Less(i, j int) bool { return a[i].Brand > a[j].Brand }
