package main

import "fmt"

func main() {
    a := [][]int{
        {4, 2, -9},
        {11, 8, 60},
    }
    fmt.Println(a)
    for i, row := range a {
        fmt.Println("Row ", i)
        fmt.Println("\t", row)
        for j, v := range row {
            fmt.Println("j:", j, ", v:", v)
        }
    }

}    
        

Output

Row  0
            [4 2 -9]
j: 0 , v: 4
j: 1 , v: 2
j: 2 , v: -9

            [11 8 60]
