package main

import "fmt"

func main() {
    slices  := [][]string{}

    row1 := []string{"go", "java", "python"}
    row2 := []string{"nodejs"}
    row3 := []string{"c", "c++", "c#", "php"}

    slices = append(slices, row1)
    slices = append(slices, row2)
    slices = append(slices, row3)

    for i := range slices {
        fmt.Println(slices[i])
    }
    
    fmt.Println("\n", slices[0][0], "\n")
    
    for i := range slices {
        for j := range slices[i] {
