Working with 2D slices in Golang

 package main import ( "fmt" ) func print2DSlice(a [][]int) { // let us iterate over 2D slice for i := 0; i < len(a); i++ { oD := a[i] // access 0th array in 2D slice for j := 0; j < len(oD); j++ { fmt.Printf("%d ", oD[j]) } fmt.Println() } return } func main() { tDSlice := make([][]int, 0) // or tDSlice:=[][]int{} tDSlice = append(tDSlice, []int{1, 2, 3, 4, 5}) tDSlice = append(tDSlice, []int{12, 32, 43, 423, 52}) tDSlice = append(tDSlice, []int{2341, 322, 323, 324, 53}) tDSlice = append(tDSlice, []int{3321, 2423, 33232, 432, 532}) tDSlice = append(tDSlice, []int{14343, 24343, 34343, 44343, 54343}) tDSlice = append(tDSlice, []int{14343, 24343, 3434334, 4434, 54343}) tDSlice = append(tDSlice, []int{4343431, 43432, 34343, 44343, 4343435}) print2DSlice(tDSlice) }
