Go tilida tuzilma massivini qanday tartiblash mumkin?

Go tilida, strukturalar massivini saralash uchun sort paketidan foydalanish mumkin. Buning uchun sort.Interface interfeysini amalga oshirish kerak, u uchta metodni talab qiladi: Len(), Less(i, j int) bool va Swap(i, j int).

Bir maydon bo‘yicha strukturalar slice’ini saralash misoli:

package main

import (
    "fmt"
    "sort"
)

type Person struct {
    Name string
    Age  int
}

type ByAge []Person

func (a ByAge) Len() int           { return len(a) }
func (a ByAge) Swap(i, j int)      { a[i], a[j] = a[j], a[i] }
func (a ByAge) Less(i, j int) bool { return a[i].Age < a[j].Age }

func main() {
    people := []Person{
        {"Alice", 30},
        {"Bob", 25},
        {"Charlie", 35},
    }

    sort.Sort(ByAge(people))

    fmt.Println(people)
}

Natijada, people slice’i yosh bo‘yicha saralanadi.
