Go: sort.slice is sorting incorrectly

package main

import (
    "fmt"
    "sort"
)

func main() {
    x := make([]int, 5)
    x[4] = 1
    x[0] = 5

    sort.Slice(x, func(i, j int) bool {
        return i < j
    })

    fmt.Println(x)
}

I want the above code to print [0 0 0 1 5]. But it prints [5 0 0 0 1]. Am I misusing this function? Or what am I doing wrong?

>Solution :

The reason why your code is showing this is because, i and j are NOT the elements of your slice. i and j are the INDEX of your slice. Thus, your correct code should be

instead of:

return i < j

The correct answer is:

return x[i] < x[j]
