How to sort slice of ints in GO?

Question

go

Sorting a slice of an int using the sort package. But the output is an unsorted array. Where is the mistake?

package main

import (
  "fmt"
  "sort"
)

func main() {
  var arr = []int{1, 3, 2}
  sort.SliceStable(arr, func(i, j int) bool {
    return i > j
  })
  for _, val := range arr {
    fmt.Println(val)
  }

}

Answer 1

Sort by index, but you need by value

package main

import (
  "fmt"
  "sort"
)

func main() {
  var arr = []int{1, 3, 2}
  sort.SliceStable(arr, func(i, j int) bool {
    return arr[i] > arr[j]    // здесь поправил
  })
  for _, val := range arr {
    fmt.Println(val)
  }
}
