检查给定切片是否在 Golang 中排序
原文:https://www . geeksforgeeks . org/check-如果给定切片是在 golang 中排序的/
在 Go 语言中切片比一个数组更强大、灵活、方便，是一个轻量级的数据结构。切片是存储相似类型元素的可变长度序列，不允许在同一切片中存储不同类型的元素。 在 Go 语言中，可以借助sliceissued()功能检查给定切片是否排序。如果给定切片已排序，此函数返回 true。如果给定的切片没有排序，则返回 false。如果指定的接口不是片类型，这个函数会死机。它是在排序包下定义的，所以您必须在程序中导入排序包来访问 SliceIsSorted 函数。
语法:
func SliceIsSorted(a_slice interface{}, less func(p, q int) bool) bool
示例:
// 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
