This seem to not work. The arr is returning only duplicate elements in your
playground url.
For example:
var arr [][]int
for mem := range m {
fmt.Println("Appending: ", mem[:])
arr = append(arr, mem[:])
}
fmt.Println("Final arr is:", arr)
the output is:
Appending: [-1 0 1]
Appending: [-1 -1 2]
Final arr is: [[-1 -1 2] [-1 -1 2]]
I am not really able to understand why the above code works so. The
"Appending" and the "Final arr" statements have different values.
