在 Go 语言中切片比数组更强大、灵活、方便，是一种轻量级的数据结构。切片是一个可变长度的序列，用于存储相似类型的元素，不允许在同一个切片中存储不同类型的元素。
在 Go 语言中，您可以借助SliceIsSorted()函数检查给定的切片是否已排序。如果给定的切片已排序，则此函数返回 true。或者，如果给定的切片未排序，则返回 false。如果指定的接口不是切片类型，则此函数将发生恐慌。它是在 sort 包下定义的，因此您必须在程序中导入 sort 包才能访问 SliceIsSorted函数。
句法：
func SliceIsSorted(a_slice interface{}, less func(p, q int) bool) bool例子：
// Go program to illustrate how to check
// the given slice is sorted or not
package main
import (
"fmt"
"sort"
)
// Main function
func main() {
// Creating and initializing
// a structure
Author := []struct {
a_name string
a_article int
a_id int
}{
{"Mina", 304, 1098},
{"Cina", 634, 102},
{"Tina", 104, 105},
{"Rina", 10, 108},
{"Sina", 234, 103},
{"Vina", 237, 106},
{"Rohit", 56, 107},
{"Mohit", 300, 104},
{"Riya", 4, 101},
{"Sohit", 20, 110},
}
// Sorting Author by their name
// Using Slice() function
sort.Slice(Author, func(p, q int) bool {
return Author[p].a_name < Author[q].a_name })
// Checking the slice is sorted
// according to their names
// Using SliceIsSorted function
res1 := sort.SliceIsSorted(Author, func(p, q int) bool {
return Author[p].a_name < Author[q].a_name })
if res1 == true {
fmt.Println("Slice is sorted by their names")
} else {
fmt.Println("Slice is not sorted by their names")
}
// Checking the slice is sorted
// according to their total articles
// Using SliceIsSorted function
res2 := sort.SliceIsSorted(Author, func(p, q int) bool {
return Author[p].a_article < Author[q].a_article })
if res2 == true {
fmt.Println("Slice is sorted by "+
"their total number of articles")
} else {
fmt.Println("Slice is not sorted by"+
" their total number of articles")
}
// Sorting Author by their ids
// Using Slice() function
sort.Slice(Author, func(p, q int) bool {
return Author[p].a_id < Author[q].a_id })
// Checking the slice is sorted
// according to their ids
// Using SliceIsSorted function
res3 := sort.SliceIsSorted(Author, func(p, q int) bool {
return Author[p].a_id < Author[q].a_id })
if res3 == true {
fmt.Println("Slice is sorted by their ids")
} else {
fmt.Println("Slice is not sorted by their ids")
}
}
输出：
Slice is sorted by their names
Slice is not sorted by their total number of articles
Slice is sorted by their ids
