Multi-Dimensional Slices

Slices of slices

Create multi-dimensional data with slices of slices:

matrix := [][]int{
    {1, 2, 3},
    {4, 5, 6},
    {7, 8, 9},
}
fmt.Println(matrix[1][2])  // 6

Each row is an independent slice. Rows can have different lengths. This flexibility is useful for irregular data structures like adjacency lists for graphs.
