Sorting slice of structs

[Sankar]

Hi

I have the following code:

type Point struct {

X    int

Name string

}

arr := []Point{

Point{1, "One"},

Point{3, "Three"},

Point{2, "Two"},

Point{4, "Four"},

}

log.Println("Before Sorting: ", arr)

sort.Slice(arr, func(i, j int) bool {

return arr[i].X < arr[i].X

})

log.Println("After Sorting: ", arr)

I wanted to see the slice of Point objects to be sorted after I called the sort function, but the slice remains unchanged. 

The play url is: 

https://play.golang.org/p/9KHfyL0xzVP

Any help on how I can get arr sorted in the above code ?

Thanks.

Change I i to I j

Simple mistake.

You have:

sort.Slice(arr, func(i, j int) bool {
return arr[i].X < arr[i].X
})

Instead use:

sort.Slice(arr, func(i, j int) bool {

return arr[i].X < arr[j].X
})

We all saw it immediately ... because ... we remember having done it too. :-)
