2d array example:

|

a[0][1] = 2
|
||||
println(a) // [[0, 2, 0], [0, 0, 0]]
|
||||
```
|
||||
|
||||
3d array example:
|
||||
```v
|
||||
mut a := [][][]int{len:2, init: [][]int{len:3, init: []int{len:2}}}
|
||||
a[0][1][1] = 2
|
||||
println(a) // [[[0, 0], [0, 2], [0, 0]], [[0, 0], [0, 0], [0, 0]]]
